David,

I am using vfp6, and am not in a position right now to recompile to 7, so, I hope my lostfocus() doesn't fire twice. This will be a big problem if it does. How can I avoid that. How else can I handle this?

So... You can't! :-) It is a bug... (Q139959)

By the way... Is there a way to create a link for an article published at KB, like a thread?

[]s!
