I just got my upgrade chip from Diamond Computer for my SpeedSTAR SVGA card
and things seem a little wierd.  I have a Gateway 2000 486/33 with their
Crystal Scan 1024ni monitor, 1M on the SVGA card, 8M, 200M HD, blah blah blah.

The problem is when I am using Windows 3.0 and put the monitor into 800x600
32k color mode there seems to be a slight flicker.  So I go and check to
make sure that I am setting VMODE correctly and things appear OK.  Also,
when I switch a full-screen DOS session my color palette gets all messed up.

Is there a bug(s) in the new drivers because Diamond wanted to get this chip
out too quickly or am I not setting something up correctly.

Thanks!
