>I try to keep video drivers up to date.

I do too, and think in this case it wouldnt hurt to look into if you haven't dealt with an updated video driver in the past 6 months. If you definitely rule out video driver, I would think you do have either a memory issue, or maybe the P90 is just too slow. BTW what OS and what version of VFP? Can you rebuild an aother projects on same machine without error? Have you run scandisk lately?
