Aah, I was suspecting this. Using menu.popup() runs the popup menu as
another "window" and the function returns immediately. This means that
the function containing the popup call will also end and thus the menu
is garbage collected unless you save a reference to it, for example in a
member variable of self. exec_ runs the menu synchronously and only
returns after the user chose an item.


Don't worry so loud, your roommate can't think.
