I realized that a key entry (like Ctrl-S) can be set to interrupt. But I was trying to see if it can be done with only a mouse click. Most commercial software do with a Cancel button and a mouse click. To me it looks more "Windows-lïke" as users do not have to type anything. But maybe it is not possible with VFP.
Thank you.
