What about the "X" on a form? It calls QueryUnload but LostFocus and Valid events are fired before QueryUnload. How would one get around doing a "Cancel" it this case?

>3. In the Lostfocus, add code to not only check for lastkey but to check the flag property and if .T. you know to bypass the validity check. You then need to set the property back to .F. for the next time.
