One more thing - if you have a special clean up routine then you'll need to handle the user quitting using a keyboard shortcut (cmd-Q) separately on OSX. Something like this...

on appleEvent pClass,pID,pSender
   switch (pClass & pID)
      case "aevtquit"
         myShutdownRoutine
         pass appleEvent
         break
      default
         pass appleEvent
         break
   end switch
end appleEvent

Not sure what's going on there. Have you tried an opencard handler? Or tried using a 'send' to trigger the change?
