Hi folks,
		I'm having the following problem: the mouse 
leaves a trail of dots on the screen in windows.

Specific Symptoms:
	- it only happens in VGA, switching to EGA gets
	rid of the problem
	- it happens in all three windows modes /s, /r, /386
	- it only happens to certain colors, the light gray
	used as the default windows background is particularly
	bad
	- the dots are about half an inch behind the cursor point
	- the dots aren't randomly scattered but fall only on
	vertical lines spaced about one quarter inch apart
	- sometimes when I unhide a window part of the screen
	is covered with these lines
	-refreshing a window gets rid of the dots, till they
	start coming back
	- I get the same problem with
		MS Bus mouse
		CompuAdd's serial mouse (a really lousy mouse!)
		Logitech Trackman
	-rest of the hardware:
		CompuAdd 25mhz 386
		CompuAdd 16bit VGA card (type A)
		Nec 2a monitor

I've tried:
	- stripping the autoexec.bat and config.sys to the bare
	minimum
	- getting the latest drivers from CompuAdd's BBS
	-trying the three different mice.

Nothing seems to work. We have other CompuAdd machines here
with the same setup except for the monitor and card. So I figure
the problem is with the card or the driver. Any help will be
appreciated.
