Thanks for the bug fix Martin. Actually, browse-url-grail doesn't need to ignore the new-window argument... -Barry -------------------- snip snip -------------------- (defun browse-url-grail (url &optional new-window) "Ask the Grail WWW browser to load URL. Default to the URL around or before point. Runs the program in the variable `browse-url-grail'." (interactive (browse-url-interactive-arg "Grail URL: ")) (message "Sending URL to Grail...") (save-excursion (set-buffer (get-buffer-create " *Shell Command Output*")) (erase-buffer) ;; don't worry about this failing. (if new-window (call-process browse-url-grail nil 0 nil "-b" url) (call-process browse-url-grail nil 0 nil url)) (message "Sending URL to Grail... done")))
