"move-frame-left" (frame-cmds.el) no longer works (Emacs 24.1.50.1)

[William Crandall]

Hello Drew,

I've been using your frame-cmds package to happily
move frames all around with keystrokes (love it).

Unfortunately, with my most resent emacs update:

   GNU Emacs 24.1.50.1 (i386-mingw-nt6.1.7601)
    of 2012-06-18 on MARVIN

while the commands are still found, they do not
move the frames, even with your latest:

;; Filename: frame-cmds.el
;; Description: Frame and window commands (interactive functions).

--------------------------------------------------


To elaborate, this code used to work (init.el):

--------------------------------------------------
(require 'frame-cmds)
(require 'frame-fns)

(defun move-frame-left-mult ()
  "Move multiple times regular unit (big steps)."
  (interactive)
  (move-frame-left 100))

(global-set-key [(meta kp-left)]          'move-frame-left)
(global-set-key [(shift meta kp-left)]    'move-frame-left-mult)
--------------------------------------------------


Emacs Help seems to know all about it:

--------------------------------------------------
move-frame-left is an interactive compiled Lisp function in
`frame-cmds.el'.

It is bound to <M-kp-left>.
--------------------------------------------------


But, when I invoke it, from keyboard or with M-x,
the fame does not budge.

To be complete, this set is found, but does nothing:

'move-frame-up)
'move-frame-down)
'move-frame-left)
'move-frame-right)

While the enlarge/shrink commands are found and /do/ work:

'enlarge-frame) ;; extend bottom
'enlarge-frame-horizontally)
'shrink-frame)  ;; pull up bottom
'shrink-frame-horizontally)


Many thanks for any suggestions,

-BC
