Message Sent when Closing Stack

[Bob Sneidar]

Hi all. 

We have gone around about this before, but I still cannot get this to work. I need to know if there is a message sent when a user clicks the close button in a window (on a Mac it's a little red dot in the upper left, on Windows a red square with an X). 

I tried before closeStack, closeStackRequest etc, and these are not getting triggered when I close the stack this way.
