I'm having a similar problem with my home computer (25 MHz 386, ATI VGA Wonder
512K card, NEC 3D monitor).  Most of the time the card works fine, except when 
my wife is using PC-Write, then the same problem you describe occurs.  Also, if
I shadow the Video BIOS, I normally lose the first character from the DOS 
command line.  I got around that by turn the feature off. Unfortunately, my
wife is unwilling to write reports with stray garbage on the screen (I don't
know why, my reports allways have garbage in them :-).  This error is 
deterministic,  I can regenerate the same garabage cells over and over by 
scrolling through the same file.

I spend most of my time using Turbo [Asm|C|Debug|Pascal] and have not noticed
this problem, though I sometimes get stray stuff on the graphics screens
(640x480 mode).  I'm not certain if its my fault or the card's fault.

As Gil mentioned, my card also passes all the diagnostic routines that ATI
supplied with the board. If anybody has an idea about what's going wrong, I'd
love to hear about it.
