When you call menu_show(), it needs the event which initiated the request
and the window it occured in.  I believe the menu package uses this event
to determine where the menu will be displayed, and which button up event
signifies a selection in the menu.  If you have a scrolling canvas, the
event coordinate space has been translated by your scrolling, and this
probably confuses the menu package.  I believe there is a routine which
translates from canvas to world coordinates, which you might want to use
to adjust the event location before calling menu_show().
