Dear Bug Team! The problem reproduced itself. This time I had (setq debug-on-error t) and have the *Backtrace* buffer available for your use: ------- *Backtrace* ------- Signaling: (wrong-type-argument number-char-or-marker-p nil) signal(wrong-type-argument (number-char-or-marker-p nil)) byte-code("..." [inhibit-read-only remove-message-hook e nil lwarn message-log warning "Error caught in `remove-message-hook': %s" error-message-string t erase-buffer " *Echo Area*" signal] 6) remove-message(message #<x-frame "emacs" 0xb37>) clear-message(message nil nil t) display-message(message "Fontifying stealthily...") message("Fontifying stealthily...") lazy-lock-fontify-walk-stealthily(nil) ------- end *Backtrace* ------- ------- *Warnings* ------- (1) (message-log/warning) Error caught in `remove-message-hook': Wrong type argument: number-char-or-marker-p, nil ------- end *Warnings* ------- I hope you find it worthwhile. I had left the XEmacs window and the error occured when I moved the mouse back into the window which caused the focus to be directed at XEmacs again after previously being elsewhere. -- Mark ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux morpheus.baushke.org 2.4.18-17.7.xsmp #1 SMP Tue Oct 8 12:37:04 EDT 2002 i686 unknown ./configure '--pdump' '--with-xface=yes' '--with-site-lisp=yes' '--with-gpm=no' '--with-sound=native' '--with-pop' '--mail-locking=lockf' '--with-clash-detection' '--debug=no' '--error-checking=none' '--with-mule=yes' '--with-database=no' '--with-ldap=yes' '--with-hesiod=no' '--with-canna=no' '--with-wnn=yes' '--with-menubars=lucid' '--with-scrollbars=lucid' '--with-dialogs=lucid' '--with-xim=xlib' '--with-msw=no' '--with-xfs=yes' XEmacs 21.4.9 "Informed Management" configured for `i686-pc-linux'.
