Skuzzy,
OK, I went back to the drivers that came with the card, and that seems to have cured the problem. The only problem now being that while I know those drivers work with AH, they don't work with a host of other games (AA, BF1942, etc.). I was actually using the 30.82 drivers before - the 4 series is for Windows XP and 2000.
So here is my next question - do you happen to know where I can find NVIDIA display drivers in between the shipped drivers (version 4.12.01.0532, 06/26/2000) and the latest 98SE drivers (30.82 02-28-2003)?
Thanks!
