Very cool solution. THANKS.

>>I have a form with several controls on it. There is a "Cancel" button that I want to be able to select at anytime to close the form and discard all changes. The problem is that if a control has focus and has valid code in it that prevents it from losing focus, the "Cancel" button is useless. Try the following code:
>>
>>PUBLIC oMyform
>>oMyform=NEWOBJECT("form1")
>>oMyform.Show
>>RETURN
>>
>>DEFINE CLASS form1 AS form
>>
>>	ADD OBJECT cmdCancel AS commandbutton WITH ;
>>		Top = 10, ;
>>		Left = 256, ;
>>		Height = 24, ;
>>		Caption = "Cancel"
>>		
>>	ADD OBJECT text1 AS textbox WITH ;
>>		Left = 10, ;
>>		Top = 10, ;
>>		Width = 100
>>		
>>	PROCEDURE text1.Valid
>>		RETURN !EMPTY(this.value)
>>	ENDPROC
>>
>>	PROCEDURE cmdCancel.Click
>>		thisform.Release()
>>	ENDPROC
>>
>>ENDDEFINE
>>
>>
>>If you enter the textbox and try to immediately Cancel, you cannot until you actually type something in the textbox!
>>
>>Anyone know how to get around this annoying behavior? VFP9?
>>
>>TIA

>>Regards,
