I'm having the same problem myslef !
Windows Xp SP1
Mem: 512M RAM
GeforceFX 5200, ASUS (v9520), 128M DDR
Maya 5 (also upgraded to 5.0.1 - didn't work either).
@dannyngan - that MEL script didn't work for me
I also seems that the bug is also causing the top window title bar to be un-drawn as-well (after 20-30 minutes of use).
@Huxley - that "Windows 2000 compatibility mode" didn't work for me either.
Note: before I have upgraded my display adpater, i had GeForce2 MX 440 64M & it's worked fine, so it is indeed strange now on Geforce
5 (FX) it doesn't work...
Plz. help solving this issue.
