Since it is simpler than the one suggested previously, I got interested in it. My ~/.emacs contains: (desktop-save-mode 1) (setq desktop-save t) (setq desktop-load-locked-desktop t) (setq desktop-base-lock-name (convert-standard-filename (format ".emacs.desktop.lock-%d" (emacs-pid)))) (setq desktop-dirname user-emacs-directory) Still, I obtain "Desktop file is more recent than the one loaded. Save anyway?" [Yes/No]. How can I avoid this question being raised?
