menu events get ignored when multi-line echo area message is displayed

[David Reitter]

Start emacs -Q. Evaluate the following two forms with C-x C-e:

(defun display-startup-echo-area-message-2 ()
    (message "%s" "one
two"))

(display-startup-echo-area-message-2)


A message should appear in the echo area. Then, select  "Help" ->  
"Copying Conditions" (with the mouse).
Result for me is that the license file is NOT displayed.

Note that it works if the message displayed has only one line.


This is a test case of a more general bug where the first selection  
of any (?) menu item is ignored after a multi-line message has been  
displayed.
It has been reported by several Aquamacs users, but the above code  
reproduces the bug with an unpatched GNU Emacs (Carbon).
