Dave,

It is very easy to reproduce and am amazed no one has reported this problem.

I know the class still being in memory was the cause of the problem. I just don't understand why VFP doesn’t handle this "still in memory" and "save to file" conflict in the IDE. It seams to me a problem with the potential to totally wipeout all class code would be and should be handled by the IDE. I have always caught the “still in memory” problem myself but it is pretty damn easy to forget if your deep into coding and testing.
