>>>We have been banging our heads on a problem that showed up at one of our new clients using our VFP 9 application.

>>>Also, those tables were on the server. Today, we had it happen to one of our client's work stations!!

Maybe you can try something like this handy little tool:

With this you'll be able to tell what has the file locked (and unlock the file too if ya want). I've used the thing for years and it's really helped me out a bunch of times when I've come across something like this.
