Trying to right-align my window on startup

[Mickey Ferguson]

On most of my systems (which are running Windows ranging from XP to Windows 7), 
when I start up emacs I want to right-align the window, with the top of the 
window set to the top of the screen and the right (or left) edge of the window 
touching the right (or left) edge of the screen.  I have an environment 
variable, emacs_alignment, that defines whether or not it should be left or 
right.  I wrote a function that does this nicely:

(defun align-window ()
  "fix window positioning"
  (interactive)
  (if (equal (getenv "emacs_alignment") "right")
      (align-window-right)
    (align-window-left))
  )

(defun align-window-left ()
  "align window to left window edge"
  (interactive)
  (set-frame-position (selected-frame) 0 0)
  )

(defun align-window-right ()
  "align window to right window edge"
  (interactive)
  (set-frame-position (selected-frame) -1 0)
  )

If I execute this function after emacs has started up, it works perfectly.  If 
I throw it into my .emacs file, it doesn't seem to do anything.  (The above 
code is found in MF-Init.el, which of course is also byte-compiled.)  Here is 
my .emacs file:

(condition-case error
    (progn
      ;;; -*-Emacs-Lisp-*-

      ; want to start editing immediately
      (setq-default inhibit-startup-message t)
      (setq-default inhibit-startup-echo-area-message t)
      (add-hook 'after-init-hook 'align-window)
     (load-library "MF-Init")
     ;;; I also tried putting (align-window) in here, but that also did nothing.
      )
  (error (progn (ding)
                (message "%s  %s"
                         "There is an error in your ~/.emacs file."
                         "Press any key to enter the debugger.")
                (discard-input)
                (sit-for 1000)
                (debug 'error error))))

Any idea how to get this function to execute properly upon the completion of 
every other bit of initialization?  Please reply directly to my email (Mickey
