>can you infer the user is resizing by testing mdown() and mouse position (from =mouseobj(lax,1)) being over a border ?

Catching the beginning of the interactive resize isn't the problem. Resize fires and I can set a flag. The problem is catching the end. Unfortunately, it's possible for MDOWN() to become .F. before all the code that responds to the resize is finished. I can't find anything that reliably fires after all resize-related activity is finished.
