>VFP is not a little program! Windows OSs are not little programs! The big surprise is that they have any stability at all!! By comparison, corporate IT projects are little programs - and they (too) are never bug free.

I fail to see your point.

With respect to some corporate IT projects, the issue may have nothing to do with little or big. Sometimes issues like the difference between exact and non-exact can mean life or death for human beings. It therefore becomes necessary to run additional tests on vendor software - particularily OSs.
