// item. If the app which opens it is Stuffit Expander, we will receive an
// ae_ApplicationDied event when Stuffit finishes and terminates.
// PowerPlant will throw an exception for any unhandled Apple Event. To inhibit
// this, add a case for ae_ApplicationDied to your application's HandleAppleEvent().
// The event does not need to be handled, just prevented from reaching
