Jim & Walter,

You got my curiosity going...I found this in Hacker's Guide:

"Timers fire when the menu is dropped down. They didn't in VFP 3.0. Timers fire in toolbars. Timers fire when a form is being dragged around. Timers fire when another application window is resized, or when Fox's window is resized. Timers fire when your application displays a message box. Awesome!"

So, apparently this changed after VFP3.
