This is in my saved tidbits stack, from a discussion a while back,  
maybe it will help:

Re: Re: saving data in a standalone before quit
(Was Re: (mac) application menu)


When you use the Quit menu item, Mac OS X sends an event to  
Revolution. You can catch this message with the AppleEvent handler or  
the shutdownRequest handler. On Mac OS X, I prefer to use the  
AppleEvent handler most of the time.

If you use either the AppleEvent handler or the shutdownRequest  
handler without a pass command, the application will not quit by  
itself (you can also lock messages and issue the quit command).

When you press command-Q, the Quit menu item should work just like  
when you use the mouse to select this menu item and you can catch the  
AppleEvent and shutdownRequest messages again. However, your script  
may catch the commandKeyDown message. If you don't pass this message  
with the pass command, your application may not quit.

There are versions of Revolution that don't pass the commandKeydown  
message because of a bug. There are also versions that don't pass the  
AppleEvent message.

If you are using Rev 2.8.1, problems with quitting are probably due to  
a script.

Re: (mac) application menu

This was driving me crazy too. After messing around with it, I pieced
the following together and it's worked for me (I am using Rev 2.6.1):

on appleEvent pClass,pID,pSender  --I got this from Ken Ray's web site
   switch (pClass & pID)
   case "aevtquit"
     answer "Save changes?" with "Don't Save" or "Save"
     if it is "Save" then
       pass appleEvent
     else pass appleEvent
     pass appleEvent
   end switch
end appleEvent

on closeStackrequest
   Global homeStack
   if the short name of this stack is homeStack then
     answer "Save changes?" with "Don't Save" or "Save"
     if it is "Save" then
     end if
   end if
   pass closeStackrequest
end closeStackrequest

on shutdownRequest --I only use this for Windows
   Global homeStack
   if the platform contains "Win" then
     if the short name of this stack is homeStack then
       answer "Save changes?" with "Don't Save" or "Save"
       if it is "Save" then
       end if
     end if
   end if
   pass shutdownRequest
end shutdownRequest
