>My VFP opens and runs ok till I open another app - Paint Shop Pro, Netscape, Visual Basic etc. Then the menus dont work. File open gives me nothing. The opposite is also the case. If I open any of my apps and then vfp, VFP menus work but not the other apps. I have tried to reinstall windows but to no avail.

I have never seen a problem like this. Have you tried phoning this one into Microsoft?

Is it the VFP menus that stop working or is it the menus in an application that you have written?
