Menubar not being refreshed

[Michael Mauger]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I created the following script (xx.el) and loaded into an emacs -Q -D
instance:

  (let (map)
    (delete-other-windows)
    (menu-bar-mode +1)
    (sit-for 0)
    (split-window-vertically)
    (other-window 1)
    (switch-to-buffer "*MENU BUG DEMO*")

    (setq map (make-sparse-keymap))
    (easy-menu-define
      my-bug-menu map
      "Refresh menu bug (on w32-only?) test case"
      '("BUG"
        ["Do Nothing" 'ignore t]))
    (use-local-map map)
    (easy-menu-add my-bug-menu)

    (insert "Is there a BUG menu in the menu-bar above?\n")
    (insert "There should be!\n\n"))

When I executed it the BUG menu was not shown in the menubar.  If I
pass the mouse cursor over the menubar, the BUG menu appears but the
menu is not drawn properly (ghosts of the old menubar options).
Switching between the two windows with `C-x o' doesn't update the
menubar as it should.  Again passing over the menubar with the mouse
shows different menu names and doesn't erase the old ones.

This has been happening for the last month or so on w32.  Not sure if
its impacting other platforms.  The menubar on w32 has become
difficult to use because it isn't updating properly.  When selected,
the menus display and act correctly.

If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
c:/emacs/emacs/etc/DEBUG for instructions.
