This is a surprising problem. Since the task list is shown I found it
hard to believe that Emacs is involved. Anyway, some questions:

- Does the problem persist after reboot?
- Does the problem show up only after you have started Emacs
- If you close Emacs does the problem disappear?

I have no idea what is happening here. If you look at the file from
Windows Explorer does the ownership etc look ok then?

Is Emacs still running when you reboot?  If so, that's because it does
not have a chance of releasing the lock on that file before it is
killed by the shutting down OS.

For Lennart's questions:
1. Yes, the problem persists after reboot.
2. The problem only occurs with emacs. For example, if emacs only covers
part of the window if I click on the outlook or firefox in the
background, alt-tab works as it should.
3. Since the behavior is tied to the emacs window, everything is okay
when that window does not have the focus, and after emacs has been
closed using C-x-C-c

For Eli's question:
I have tried it both shutting down emacs and doing a reboot and by doing
the reboot with emacs running. In both cases, I get the PID message when
the system comes back up.

I am the owner of the file.

Thanks for you attention

Can you launch a task manager before rebooting and see if Emacs or
emacsclient is still in the air?

Also, what happens if you exit Emacs and then start it again: does it
complain then as well?

Could you please try and see if this problem is there if you start Emacs
with

   emacs -Q

Lennart,

There is no problem if I start use "emacs -Q" from the command line in
C:\apps\emacs\emacs\bin

The problem occurs if I start it with a simple "emacs " command.

The problem still occurs if I use the icon in the systray. That points
to C:\Apps\Emacs\emacs\bin\emacsclientw.exe -n

Does this point to a problem in my .emacs file or something else?
Thanks.

Hi Bill,

It tells us that the problem is related to your setup, not that the
cause necessarily is there.

Could you try to find out what in your .emacs that causes this problem?

Let me be sure I understand what you are saying: Rebooting the
computer has nothing to do with this problem; if you exit Emacs and
then start another Emacs session, the same message appears.  Right?

If I eliminate the entire (custom-set-variables ... definition the
ALT-Tab problem goes away.
If I comment out " ;(desktop-save-mode 1)" the pid complaint ceases.

Here is the custom-set-variables definition:
;(custom-set-variables
;  ;; custom-set-variables was added by Custom.
;  ;; If you edit it by hand, you could mess it up, so be careful.

; )

How does one comment out individual pieces of the custom-set-variables
definition? My lisp experience is of the cut and paste variety.

Yes.

Commenting out various pieces of my .emacs file narrows the problem to
the (desktop-save-mode 1) line. If that is commented out the PID problem
goes away. If I leave it in, the problem occurs.

I copied that line from the emacs documentation.

Thanks.

Please try commenting out only the line above.

Just comment them out line by line here. Make sure the parenthesis match.

But I can't see how any of these affect Alt-Tab. Maybe w32-meta-style,
see above. (If so it is a bug I should fix.)

This is the corresponding parts of my customizations:

(custom-set-variables
  '(cua-mode t nil (cua-base))
  '(emacsw32-max-frames t)
  '(emacsw32-mode t)
  '(emacsw32-remove-emacs-print t)
  '(emacsw32-style-frame-title t)
  '(htmlize-view-print-visible t t)
  '(menuacc-mode t)
  '(org-CUA-compatible t)
  '(org-replace-disputed-keys t)
  '(ourcomments-ido-ctrl-tab t)
  '(recentf-mode t)
  '(w32-meta-style (quote w32-lr))
  '(w32-print-menu-show-print nil)
  '(w32-print-menu-show-ps-print nil)
  '(w32shell-shell (quote cmd)))

Lennart,
I copied your custom-set-variables defn into my .emacs and the ALT-TAB
problem reappeared.
When I commented out the w32-meta-style line, the problem goes away.

Thanks.
