executing a script upon close/hide window

[hollyheadhunter]

how can i trigger a script when a user closes a window? i thought one way would be to use a Custom Menu for "Hide Window" but i don't seem to be able to make a Custom Menu for items in the Window menu...

It's a custom menu for 'File->Close' menu.
