>>>With one compiled program (a small exe with nothing included, just the main) when run on WIndow 95/98 a number of other programs crash when the exe is open. We've had problems with Explorer, Outlook, Eudora and Adobe PhotoDeluxe so far (just two installations) We found no problems using NT.

OK. What version of VFP? Are you using any ActiveX controls? Does it happen when just a particular form is open, or just the application. Does it happen when the app is minimized? The first thing I would suspect is video driver problems.
