>I just tried a listbox, and a textbox, neither fire unless data is changed. VFP 5.0 But then I'm having all these other troubles with error events not firing also, maybe I need to reinstall ? Is there any global setting that affects valid execution that I don't know about ?

Are we talking about the same thing?

I created a test form. I put 2 textbox controls. I put WAIT WINDOW 'HERE' in the Valid() event of those 2 controls. I run it and press TAB to move between them. Each time, the VALID() is firing.
