This is a perfect situation for a Global App Object. You instantiate this prior to calling your first Form and attch the Timer to it. Set the Timer's interval to whatever and decide what criteria to use to determine Inactivity. It will always be measuring elapsed time regardless of which Form is running, since it is Global to all.

I would also have to go back through all my screens and make sure I have dodefault() in any that I use the keypress in. (And that is a whole lot of screens, over 150.)
