Fwd: Best way to set up an idle timer - not like this

[Devin Asay]

Wait! What seemed to be working at first is not. It seems okay until 
you start examining the pendingMessages. For some reason the sent 
messages start queuing up rapidly as soon as you start mousing around 
in the stack. Obviously the cancel command in the resetLogout handler 
is not getting all of the pending messages. But I can't figure out 
where all of these pendingMessages are coming from.

Any experts out there in this area that can tell me where I've gone 
wrong?
