       Since all button press/release events are catched by the windows frames, there is some 
       side effect with GTK menu. When a menu is opened, any click on the window frame is not
       detected as a click outside the menu, and the menu doesn't close.
       To avoid this (painless but annoying) behaviour, we just setup a no event window that 
       "hides" the events to regular windows. 
       That might look tricky, but it's very efficient and save plenty of lines of complicated 
       code.
       Don't forget to delete that window once the menu is closed, though, or we'll get in 
       trouble.
