Yes, it does seem as though it would work. OTOH, if the form has an event
handler, just be sure to handle the frmClose event. When you hit the Calc
silkscreen key (the example given above), Palm OS sends your app an appStop
event. When your app receives this event, it should be calling
FrmCloseAllForms() on its way out. That will send the frmClose event to all
open forms, and there you go!
I've used this technique in my apps with good success.
