>I presume you've downloaded the latest video driver for your card, and tried different resolutions and color depths?

No, I haven't, and that could help - but I'm really kind of intentionally looking at worst-case scenarios in the NT testing, since the app wiil have to run on a variety of machines/monitors when we move fully to NT. So I'm looking for fixes inside vfp, if at all possible.

>I seem to recall M$KB having something on this. It suggested some method of forcing NT to rebuild a file....

I'll take a look next week...with a topic as wide as this, I usually hope UTers can jump in with a fix before I expend a lot of time searching articles :)
