I also noticed that on older games my display jumps between the game and the desktop when running the GUI version. While the game runs OK F@H cannot adjust the PixelFormat and abends.
I now turn it off before older games, and run the console version on another system.
Sorry to all for the misinformation. My daughter and my wife both play a few games om their computers, and I haven't heard any complaints, so I assumed there would be no problems. The only game I play is MOHAA, and I haven't played it in months. I guess I'll dig it out and try it to see what happens. Sorry all.
At this rate we should overtake Team Fark (currently #144) in 1.7 months - with continued growth, we could do it in 30 days.
