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.
