Hi.  I am running Borland C++ on my 286 clone.  It has a Paradise 16-bit
VGA card.  After I installed window drivers for Paradise card (by copying
the PVGA480.DRV to c:\windows\system\vga.drv)  (so thatI can have 256 colors 
in 640x480), I started window in standard mode.  Then I ran 
"Turbo Debugger for Windows" in Windows 3.0.  Everything was fine then.  
But after I exitted Turbo Debugger for Windows, I had a big problem with the 
display.  The display was screwed  up.  It seems it has sync problem, and 
the Turbo Debugger won't restore the display parameters for windows 3.  

I have the same problem when I run in 800x600 and 1024x768 mode.

However, if I run window 3 using the original VGA driver provided by window 3,
(only 16 colors), everything is fine.

Does anybody know what is happening there?  Or does anybody have the
same problem as I have?  Is this a bug in Turbo Debugger?  Or this is a bug
in paradise drivers?
