M-x shell RET 3. C-x C-b It appears that, for the *shell* buffer, mode-line-process is initialized to ":%s" in "define-derived-mode comint-mode" (comint.el line 622), and this particular value is what format-mode-line (called from list-buffers-noselect, buff-menu.el line 751) is complaining about. But I'm not sure how to debug it further. -- Bob Rogers http://rgrjr.dyndns.org/
