I hadn't tried the invalidate() followed by the repaint(), but unfortunately, that
didn't solve the problem either (though it did improve it over what it was prior
to the show() method approach...)

If you get a few moments, try adding another button that adds a menu to the
menubar and see if that works for you.  When I add a menu, it doesn't show up
until I click the JFrame's border.  When I remove a menu, I end up w/ a 'hole' in
the menubar where the removed item was.

The general scheme that I have is as follows:
MDIFrame extends JFrame
MDIDesktopPane extends JDesktopPane
MDIDesktopManager extends DefaultDesktopManager
MDISheet extends JInternalFrame

MDIDesktopPane is added to MDIFrame's ContentPane.  MDIDesktopManager is set as
MDIDesktopPane's DesktopManager and calls MDISheet.setupMenu() whenever a sheet is
activated and calls MDISheet.cleanupMenu() whenever a sheet is deactivated or
closed.  I add/remove menu stuff to/from the frame's JMenuBar in the sheet's
setup/cleanup methods (sheets are subclassed from MDISheet...).  Seemingly endless
combinations of paint, repaint, update, validate, invalidate, show and quite
imaginative combinations of four-letter verbal commands have failed to cause menu
stuff added/removed in setup/cleanup to show up w/o needing to click around in the
menubar or resize the frame.  The one exception to this is calling
MDIFrame.show(), which kinda sucks... :-)

I appreciate the help!!
