This program is a desktop manager which allows you to create multiple desktops and switch between them. Program is useful to persons who perform different things with one computer at the same time. You can group applications. One desktop for one group of applications. You can create a desktop for seldom used programs. Or you can create a desktop for programs that you have to run, but you don't want to take space from your desktop. Or, if you want to hide running programs from others. Or, if you want to run multiple shells at the same time. MultiDesktop Manager has many user interface languages.
MultiDesktop Manager is freeware.
If you are a Japanese user and want to read this help in your own language, use following links.
If you see square boxes in the application when you choose Japanese language, you need to install Japanese fonts. See instructions from your operating system. MultiDesktop Manager uses Tahoma font if it is available. Otherwise it uses Arial. English version of Windows NT 4.0 is not capable of displaying menus in Japanese because its system font does not support Japanese glyphs.

MultiDesktop Manager will run only on Windows NT 4.0, Windows 2000, Windows XP or later because program uses features that are available on Windows NT based OS, but not on Windows 95, Windows 98 or Windows Me. It uses some features that does not exist in Windows NT 3.1 and 3.51, so it will not run on earlier NTs.
Most of the Virtual Desktop programs run also on Windows 95/98/Me. Windows 95/98/Me has only one desktop so all windows are on single desktop. Virtual Desktop program just show and hide windows (I think).
You can create as many desktops as Windows NT accepts.
You can choose any application as shell application. Explorer (default), Program Manager, File Manager and Internet Explorer are predefined. If you wish, you can create a desktop without a shell application as an empty desktop.
You can switch between desktops with mouse by clicking tray icon and selecting a desktop from menu or with keyboard by pressing Ctrl-Alt-Left arrow or Ctrl-Alt-Right arrow.
Ctrl-Alt-D opens a menu for operations.
You can run any program on any desktop by pressing Ctrl-Alt-R which shows a dialog where you can enter name of the program. This is also possible using mouse by clicking tray icon and choosing 'Run...' from menu.
You can select the language of the user interface. Language changes on every open window online. Supported languages are listed later. By default MultiDesktop Manager uses your Regional Settings from Control Panel. If your locale is not supported by MultiDesktop Manager, MultiDesktop Manager uses English. You can save default language.
Setup has two phases.
First you run the setup program MegaScale MultiDesktop Manager Setup.exe. This program is used to choose the location for the program files and copy program files to chosen location.
In single computer environment the best location is MultiDesktop Manager-folder under your Program Files-folder. This is the default location.
In the office you have two possible solutions. First is to copy the setup program to server. Then people will run this program and setup their private copy in their computers. Second is to place program files on server using setup program. Then people will run shared copy of this program. They just run the program from the server.
Setup will detect the location of the previously installed version. This cannot be changed. Also, it detects if you are currently running other version. You have to close currently running version so the Setup can copy new version over existing one. If somebody else is using old version on shared resource the copy fails and error message is displayed. It does not detect if you are installing older version over newer version.
This is built in feature in MegaScale MultiDesktop Manager.exe.
If you have not installed this program yet, program asks you which language you want to use and few other things.
When program starts it goes directly to tray. This program does not have a main window.
There are two ways to uninstall this product.
Use Add/Remove Programs in Control Panel and select MegaScale MultiDesktop Manager from the list and press Add/Remove... or you can use Uninstall...-menu item from the popup menu of this program.
Uninstalling does the following things:
You cannot remove program from installed applications, if other users use this program in this computer. This is checked from registry. Other users use this program if they have registry settings.
You may choose to delete all the program files. If you run this program from server, you cannot delete files.
Also you can choose to delete the program folder.

Windows Explorer has Run-dialog too, but it does not show up on desktops you have created, if you use Win-R. It always opens on default desktop. If you don't have Win-key in your keyboard, you don't have this problem. If you are on a desktop which does not run Windows Explorer, you probably cannot open Windows' Run-dialog. These are the reasons why this program has Run-dialog.
You can enter name of the program without the location of the program file, if program is registered properly. For example Microsoft Word and WinZip are registered properly. This means that you can enter winword or winzip.

You can switch desktops with Alt Gr-Arrows too.
When creating extra desktop with Active Desktop Explorer as Shell, Explorer thinks it has crashed and enters into Recovery mode. I think this is a bug of Explorer. To avoid this don't use Active Desktop or use another shell instead of Explorer on other desktops.
If you use Hot Keys of Explorer, they will only work on Default desktop. For example pressing Win-R opens Run dialog, but always on a Default desktop. It will not open the dialog on other desktops. If you press Win-M to minimize all windows in current desktop, all windows on Default desktop will be minimized. These are limitations of Explorer.
Tray icons are not copied to the tray of other desktops. Mail notifications (icon in tray) etc. will only show in Default desktop or in the desktop where the program is running on. Icons may show on other desktops if program is designed multiple desktops in mind.
In general, all messages are displayed on the desktop where the program is running on.
You can not move windows from one desktop to another desktop. Window belongs to that desktop where it was created on.
When you logoff, all the desktops you have created are destroyed.
When you logoff, all explorer folders are saved from every desktop (if this setting is on in Explorer). When you logon, folders are restored, but all onto the Default desktop.
If you don't use Explorer as a shell in desktop you have created and then maximize running program, it will not fill the screen. Windows will reserve space for taskbar even when current desktop does not have it. Also when minimizing an application, it will not go bottom of the screen. Again, space for the taskbar is reserved by Explorer. If you have e.g. two desktops and move tray in one desktop to another edge of the screen and then you go to other desktop and then maximize one window, it will use settings from previous change (i.e. the last setting in the computer). I think this is a "feature" of Explorer and Windows. Windows does not check current desktop when it resizes the working area; instead it uses one setting for all desktops.
If you try to use Windows NT Task Manager's Applications-tab to "Switch To" the selected application and the application is on another desktop, it does not do nothing. Windows NT Task Manager cannot Switch To the selected application, if application is on another desktop.
If you run 16-bit program on non-Default desktop, it may start on Default desktop. True story. I am not sure does this happens always. Or only when NTVDM was already running on Default desktop.
When you start program on non-Default desktop, that program may start program on Default desktop. True story. Second program wasn't 16-bit program. It looks like that the name of the desktop (Default) was hard coded into the application.
When you create a new desktop and use explorer as shell, it may run programs on Startup folders again. This depends on version of Windows NT. I believe that standard Windows NT 4.0 behaves like this.
Windows 2000: Explorer seems to open search on Default desktop. I have a setting that runs Explorer windows in separate processes. When I start a search, it will use process of existing Explorer. But, somehow it decides to use Explorer on Default desktop, not the current process on current desktop. I wrote and noticed this on January 17th 2001. At that time I had no service packs installed. Today, on February 6th 2002, I tried this again and it worked as it should work. I have service pack 2 installed.
One person started second desktop with Internet Explorer. So, it was only Internet Explorer running. Then he clicked to link in Outlook Express, which was on Default desktop. He wondered why the web page does not load. Outlook Express opened the web page in Internet Explorer on second desktop. I verified this on January 17th 2001. Is ShellExecute-API-function the reason for this bad behaviour?
At work I had one peculiar problem with Outlook on May 15th 2001. I had Outlook running on second desktop. On that desktop in Explorer I right clicked a file and chose Send To Mail Recipient. It opened the mail window, but I could not choose a recipient, because "To..." didn't work. It just beeped and gave a error message. I went to the Default desktop and did the same (Outlook still on second desktop) and it worked. Weird!
Most of these problems yield to Microsoft. They do not test programs on Windows NT with multiple desktops.
Want to run shell as another user account.
Want run program as another user account.
Create a desktop automatically at startup.
Run selected programs automatically on desktops created at startup.
Want to translate the application to my own language. Please, send me e-mail, if you wish to do the job.
Want to choose desktop directly with some hotkey (like in Linux, I've heard).
Want to see the name of the current desktop.
Want to see programs running on specified desktop in a list. And choose one.
Want to close/delete desktop.
Want to rename desktop.
Want to hide icon from tray so people don't see it. I use keyboard for menus and changing desktop.
Want to configure hot keys.
Destroy all desktops when program closes (option).
Option "Do not show message when another copy is already running".
Tiny windows with screenshots.
I have received other feature requests, but I have not added them into this list. I should.

Inaccessible desktops are also ignored when rotating desktops with
MDM crashed when Chinese text was entered (actually pasted) in Desktop name field in New Desktop dialog. The bug was in call to a single byte version of one RTL-function. I did not remember to change this to Unicode when I made an Unicode version.
Thanks to Michal Řeháček who found these anomalies.
|0.3.0.3||27.11.2000||Added Spanish (thanks to Andrés Javier Purriños).|
|0.3.0.4||13.12.2000||Added Czech (thanks to Michal Řeháček). Problems displaying all characters. MS Sans Serif font does not contain all needed characters. I need to change the font. Tried Tahoma which works, if user has it.|
|0.3.0.5||15.12.2000||Decided to use Arial on all dialogs. Arial is available on standard Windows NT 4 and Windows 2000. Now the only problem is in popup menu on Windows NT 4.0 which does not display all characters properly on normal English version OS.|
|0.3.0.6||17.12.2000||Arial did not work correctly with Chinese text. Decided to use Tahoma on all dialogs. Added modified version of Czech translation.|
|18.12.2000||If system does not have Tahoma font, Arial font is used in dialogs by changing font dynamically.|
|19.12.2000||Tahoma font was not a good choice for dialogs. If user did not have Tahoma font, OS decided to use System font and it resized the dialog for the bigger System font. Now all dialogs use Arial font by default. If Tahoma font is available in the system, font in dialog is changed to Tahoma. This works nicely.|

|0.3.2.2||26.10.2001||27.10.2001||A little help for users who use shell replacements. Usually Windows Explorer starts as shell. It is controlled by value of "Shell" in registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon". Normally it's "Exlporer.exe". This is a system wide setting. When you logon, specified shell will be executed. Some users use e.g. geOShell as shell, so they have a value "geOShell.exe" (usually with a full path) in "Shell". When they login, geOShell will be launched on Default desktop. When they create a new desktop and choose Explorer as shell application, Explorer executes as a normal file manager window. Why not as shell? Explorer reads "Shell" value and it sees that it is not shell, so it executes as file manager window. MDM changes this. When you create a new desktop and choose any application as shell, MDM temporarily saves it as shell in the registry. This is only done if user has enough access rights to save the registry setting. After the shell is running, "Shell" setting is restored. I heard of these problems from Takayuki Kawamoto, who also tested that my code worked in his system. He uses at least two shell replacements: LiteStep and geOShell.|
|27.10.2001||I figured out that my code does not work in every situation. To demonstrate this I created a new desktop with Notepad as a shell. Then I executed Explorer. Guess what? Explorer thought that it is a shell, as I expected. Two possible solutions. First is to change the "Shell" setting every time I run an application. This solves the problem if application is executed in MDM. What if application is executed in another application? To solve this I could modify "Shell" setting every time user switches to the desktop. The problem with this is "What if the computer crashes or MDM is terminated when there's a wrong setting?" Imagine that Notepad was chosen as shell and then you terminate MDM and logoff. When you logon, Notepad is launched. Nothing else. What would you do then?|
|0.3.2.3||28.10.2001||28.10.2001||Added Japanese (thanks to Takayuki Kawamoto). Modified the size of some items in dialogs. Few texts are too long.|
|0.3.2.4||28.10.2001||28.10.2001||Few modifications to Japanese texts. One text is still too long in my Windows 2000. Takayuki said that it was OK in his system. I tried this version at work in one computer (Windows 2000) which didn't have Japanese fonts. There were square boxes all over. Also, in this computer the fonts were resized to 109%, so MDM didn't display everything correctly.|
|0.3.2.5||30.10.2001||30.10.2001||It seems that I have fixed size font and Takayuki has variable size font. The too long phrase is now shorter than before, so it's fully visible in my system. MDM remembers which application is a shell, and when new process is launched from Run dialog, MDM temporarily changes "Shell" in the registry. Now if you use e.g. Notepad as shell and launch Explorer from Run dialog, Explorer is executed as file manager window. This does not work, if you launch Explorer from other application (it launches as shell). When you close MDM and then run it again, MDM does not know which application is a shell, so described technique might not work. Anyway, it worked in my case. MDM temporarily saved an empty setting in "Shell" in the registry and Explorer didn't launch as shell.|
