How do you track the mouse and close the menu when the button is released
outside of the window without a grab?  The user can use alt-Tab to switch
apps while the mouse button is still pressed.  In this case, the app never
gets a mouse up event until it gets the focus again.  This is less common
than just using the keyboard, but it can happen.

Another problem is that the menu window can't take the focus away from
their parent window because the title bar on the parent window will change
color to indicate that it longer has the focus (this was a bug in gtk at
one point that has since been fixed).
