I tried loading Janes USAF on XP Professional. Yes it had the problem in the graphics setup options. But then it locked up my PC completely, needed reset button! I deleted everything to do with USAF and reinstalled. Same happened again, I gave up. Maybe I'll try to find a patch and try again sometime. I can't go back to 98 now, shame, it was a good sim. Anybody heard of a sure fix, please let me know.
