Mike,
If you don't handel the frmCloseEvent, Palm OS cleans up for you.
According
to the information on frmCloseEvent in the Palm OS SDK Reference, which
can
be found on-line at:
http://www.palm.com/devzone/docs/palmos/EventRef.html#609539
frmCloseEvent
The form routines FrmGotoForm and FrmCloseAllForms send this event.
FrmGotoForm
sends a frmCloseEvent to the currently active form; FrmCloseAllForms
sends a
frmCloseEvent to all forms an application has loaded into memory. If
an
application doesn't intercept this event, the routine FrmHandleEvent
erases the
specified form and releases any memory allocated for it.
