Hi Peter,

I'm not sure about Problem 2 but regarding Problem 1, you need to trap an AppleEvent in order for a standalone to perform some activities before quitting. For example, put this script in your main stack script and when theClass = "aevt" and theID = "quit", you can successfully trap the program before it quits. eg.

on appleEvent theClass,theID
  if theClass = "aevt" and theID = "quit" then
    -- do something
    quit
  end if
end appleEvent

Best Regards,

Mike
