None of those things happen in the program. Since this is not part of my production environment and a simple restart of the program gets me back on track, I'll drop the topic for now. I've recompiled so that the source code should be available to me if it ever recurrs and I'll figure it out then.

I appreciate your effort.......UT rocks
