Menu windows grab the mouse pointer globally. Therefore other windows
cannot receive events.

The grabbing is not a bug but intentional. That way you can safely click
anywhere on the screen to close the menu without action.

If you really need to work around this, then consider implementing your
own menu widget instead of using the one of GTK.
Or you could run a timer that regularly checks if the mouse pointer is
still within the application window (gtk.Window.get_position(),
gtk.Window.get_size()) and close the menu if not.
