Heretic! Not on 7.0 yet???:-) (Just between you and I, I haven't been able to downoad 7.0 yet. Been having problems with the MSDN site. I'm just going to wait until the next shipment< g >).

Seriously, the only time I ran into something like this was when I inadvertantly set LockScreen to .T. prior to showing a modal dialog that was based on a form class of my and forgeting to set it back to .F. But you've said that LockScreen isn't the issue.
