I don't understand all the code, but I think I understand what your tring to do. However, the menu won't come up at all once disabled.
If this can't work I can just go with ESC calling up the Quit menu (return to title, return to windows, cancel) What script woud call the quit menu?
I wonder if there is code in the Ring Menu script itself that is also disabling the entire menu if menus are disabled. As little as I can understand of it, it dosen't help that it's a partaly translated script
