>>In the misbehaving app, Borderstyle is "3 - Sizable (default)" in the scx and in its parent form classes, so there is no Borderstyle property in the SCX record for this form. I even browsed the .scx to make absolutelt sure. So Calvin's 04/07 blog explanation doesn't apply.

>>One strange thing is that the border sometimes appears, sometimes not. Usually it appears the first couple of times I open the form after starting the app, then the same form will open without the border. Seems like it would be consistent if it were a security issue. Very strange.

>This is starting to sound like a video issue. What video card are you using? Does it support Vista and Aero? Do you have the latest drivers? It took the major card makers a while to iron out support for Vista (and they're probably still working on it), so drivers that came with Vista might not be the best.


Good idea. One has an ATI Radeon X300 card, the laptop has an NVIDIA GeoForce 8400M GS card. I just installed the latest Vista drivers from the manufacturers, no change. Also tried turning UAC back on, and turning off Norton Internet Security, still no luck. And I have made sure that there is only one VFP9.EXE on the entire machine and it is 5815.
