desktop-read issue on XP - emacs 23.2 or 3

desktop-read issue on XP - emacs 23.2 or 3

[AlFire]

Hi,

With .emacs narrowed down to following:
(custom-set-variables
  '(desktop-save-mode t))
(desktop-load-default)
(desktop-read)

I noted a very weird question upon start up (only Windows, Linux is fine):

"Warning: desktop file appears to be in use by PID %s.

The PID indicates the emacs itself I am trying to bring up. Any idea 
what is wrong? It is really annoying.


Thx, Andy

I think in Emacs 22 and later the way to activate `desktop' has changed.

I think you just need:

(desktop-save-mode 1)

in your .emacs nowadays.

Is it possible you are using an older config?  Perhaps a read of the 
info page on desktop would solve ye problem.

Actually - forgive me - I am only speaking about Emacs 22 here.  I've 
never used Emacs 23.

I don't use desktop so I can only speculate.  IIUC,
`desktop-load-default' is obsolete since Emacs 22.1.  What happens if
you omit it?  The very problem occurs when you call `desktop-read' which
does

		   (or (null desktop-load-locked-desktop)
		       (not (y-or-n-p (format "Warning: desktop file appears to be in use by PID %s.\n\
Using it may cause conflicts.  Use it anyway? " owner)))))

so simply typing "y" should load it.  But maybe Emacs could check
whether it is the owner of that PID.  Are you sure there's no other
Emacs process around?

that was it. I replaced:

(setq desktop-enable t)
(desktop-load-default)
(desktop-read)
(defun desktop-auto-save ()
    "Added to auto-save-hook so the desktop is not lost."
    (desktop-save "~/")
    (message "Wrote desktop.")
    )
(add-hook 'auto-save-hook 'desktop-auto-save t)

by:

(desktop-save-mode 1)


and all works. And just for the record - the versions in subject I put 
are wrong - it supposed to be 22.2.1 and 23.0.60.1.

I did not help - I replaced all existing solution by singe
(desktop-save-mode 1)

yes, it was first thing I checked :-)
