Tim,
I have a Windows XP system with a Radeon 9600 XT AGP card. Fractint
works fine with it.
As an aside, you may recall that many people on this list, including you,
tried to help me with a problem I had when I first got the card. Fractint
would not give me any resolutions over 640 X 480. Nothing I tried
helped.
However, I recently purchased a new monitor. It's a SyncMaster 173P
LCD display. I can now get resolutions up to 1280 X 1024. My
previous SONY monitor was certainly capable of the handling these resolutions,
so I don't know why changing the monitor should have had an effect. Maybe
this will give you some ideas about your own situation, though.
