Hi, I can now confirm that the "pure build" of GNU Emacs 24.4
distributed for Mac OS X from http://emacsformacosx.com/ on 2014-10-20
contains the same bug that I earlier reported against Aquamacs at
http://comments.gmane.org/gmane.emacs.aquamacs.devel/992
(copied below).  The bug is new in Emacs 24.4 (it wasn't there
in Emacs 24.3).  I've reproduced it both on OS X 10.9.4 and OS X 10.7.

> Hi, I'm on a machine running OS X version 10.9.4 and I use
> System Preferences / Accessibility / Zoom to get 2x magnification
> of the entire screen.  When Zoom is turned on, clicking on the
> menubar in [Emacs] usually results in the wrong menu popping up.
> For example, clicking on "Window" causes the "Edit" menu to pop up,
> clicking on "Options" causes the "File" menu to pop up.  It seems
> to be interpreting the click as further to the left of where it
> actually is.  The menu does not STAY popped up however - as soon
> as the mouse is released, the menu goes away again.  The only way
> to access the menu options properly is to (1) click on the leftmost
> "[Emacs]" menu (or the Apple icon), (2) drag the mouse over the
> other menus - if you do THAT, you can get any menu you like to pop
> up and stay popped up.  Which is a nice workaround.  But it would
> be better if you could click on just any menu and have it pop up.
> 
> The bug hapens ONLY when Zoom is turned on.  I am using it at 2x
> magnification, which I set in Zoom's "More Options".  I set
> Minimum Zoom 0, Maximum Zoom 2, and pressed the Zoom In shortcut
> (which by default is Command-Alt-Plus).
> 
> This is the first time I have known ANY application to behave
> differently when Zoom is on compared to when it is off.  I didn't
> know the applications even KNEW about zoom (I thought it was all
> 'under the carpet' as far as applications are concerned).  Maybe
> [Emacs] is trying to override the behaviour of the menu bar at
> such a low level that it's being tripped up by this.
