you can also connect to the map event which is useful for some things.
i often use the map/unmap events of combo popwin's to be able to reset
the contents and/or retrieve whatever choice was made (the combo has
such a terrible API that this was the best i could do). ditto for
menus that need to be completely dynamic.
