last-nonmenu-event returns a bad value when submenus are involved.
This applies to 22.2 and the current CVS. As an example:

emacs -Q

;; Evaluate this code:

(defun bar ()
  (interactive)
  (message "%s :: %s" last-nonmenu-event
     (posn-window (event-start last-nonmenu-event)))
  (sit-for 5))

(global-set-key
 [down-mouse-2]
 '(menu-item "foo"
             (keymap "foo"
                     (bar menu-item "bar" bar)
                     (submenu menu-item "submenu"
                              (keymap "submenu" (bar menu-item "bar" bar))))))

C-x 2
Put "scratch" in one window, "messages" in the other.
Select "messages" window.
Move mouse over "scratch", but do not select it.
Press mouse-2, and select the "bar" menu-item.


When called from the top-level menu, `bar' correctly returns:

(down-mouse-2 (#<window 3 on *scratch*> 534 (251 . 101) 2649593899 nil
534 (27 . 6) nil (8 . 11) (9 . 15))) :: #<window 3 on *scratch*>


When called from the submenu, `bar' returns a bad result:

bar :: #<window 7 on *Messages*>

The window is wrong, etc.
