>So, you din't see this error yet? I see in parallel thread that it appears at 'Quit' point only. Is this true?

I think I noticed that too. So it's not exactly catastrophic, but can make your app look kind of tacky :)

I've haven't seen it on my machine at quit, but only once or twice in development crashes in my 6 beta. I haven't tested a vfp6 app, though, in a run-time non-vfp machine...
