Actually, your DV 2.32 DOES have support for 800x600 resolution, IF you run it in 16-color mode. Just choose '800x600x16' in your Windows 3.0 setup, restart Windows under DV, switch away from it and then switch back and the screen will be fully restored. I just tried this 15 seconds ago and it works. In addition, you can run ANY resolution under Desqview, you just can't switch away from most extended resolutions and expect them to be properly displayed when you switch back. I can, for example, run Windows in 1024x768x256 under DV in standard mode with no problem; but if I switch away from it and then switch back I simply have to bring up a full screen window to restore the display. Other than that inconvenience there are no problems. (BTW, I have QEMM 5.11 and DV 2.31.) Here's a couple Q&A's from the Quarterdeck White Pages: ]Q: Is Desqview compatible with Extended VGA Modes? ]The highest resolution in the IBM VGA Specification is 640x480. ]Some VGA cards have the capability of displaying resolutions of ]700X420, 800X600, and 1024X768. Since these modes are not ]standardized and most of the manufacturers of these cards ]implement these resolutions differently, DESQview cannot fully ]support these modes. ]DESQview will support 640X480 in that it can save and restore the ]screen when programs are switched away from and back to. It can ]also virtualize this resolution, meaning it will allow a program ]that writes directly to the screen to stay running in a small ]window or in the background without bleeding through the ]foreground window. ]DESQview can Save and Restore 800X600 on some VGA cards if ]Graphic Pages in Change a Program is set to 4, but it cannot ]Virtualize it. It's sometimes O.K. to set Runs in Background to ]Y and Virtualize... to N for purposes of printing in the ]background if the program doesn't do screen updates or only does ]minor screen updates while it's printing. ]Q: Why does only half of my screen get restored in some programs? ]When a program is switched away from and another program is put ]on the screen, DESQview (not the program) saves that screen ]away. When you switch back to that program DESQview redisplays ]on the screen what it had saved. This saving and restoring ]process is done in Expanded memory if available. Some programs ]use more video memory than others. DESQview has to have a larger ]buffer available for those programs. If the buffer isn't large ]enough, DESQview may only find enough room to save part of the ]screen. When restored only part of the screen gets restored. ]The amount of memory used for this buffer is set in the Change-a- ]Programs Advanced Options. The fields labeled "Text Pages:" and ]"Graphics Pages:" may be set from 1 to 4. Each text page takes ]about 4K of memory and each graphic page requires 64K of memory. ]If only part of your program's display is getting restored, try ]raising these numbers. Stephen M.
