Hi John Paul, this does it for me in vanilla emacs-version "21.4 (patch 6) \"Common Lisp (Windows [1])\" XEmacs Lucid" (global-set-key '[(control ?x) (control ?b)] 'ibuffer) (setq debug-on-error t) (setq ibuffer-default-shrink-to-minimum-size t) (setq ibuffer-use-other-window t) (dotimes (row (- (frame-height) (length (delete-if (lambda (buffer) (string-match "^ " (buffer-name buffer))) (buffer-list))))) (get-buffer-create (format "tmp-%d" row))) ;eval the above and you'll get: ;Signaling: (error "Won't change only window") ; enlarge-window(1) ; ibuffer-shrink-to-fit() ; ibuffer-update(nil) ; ibuffer(nil) ; call-interactively(ibuffer) jpw> Hmm. Maybe it helps to change the test at the start of jpw> ibuffer-shrink-to-fit to use ibuffer-window-list, like so? jpw> (when (> (length (ibuffer-window-list)) 1) ... Hmmh, the following from emacs-version "21.4 (patch 6) \"Common Lisp (Windows [1])\" XEmacs Lucid" looks interesting (and scary): `scroll-pos-visible-bug-p' (buffer: *Hyper Apropos*, mode: Hyper-Apropos) Variable: value: nil A flag, set when this version of GNU Emacs has a buggy version of the function `pos-visible-in-window-p' that returns `nil' when given `(point-max)' and `(point-max)' is on the last line of the window. Currently, this flag is set for all versions of Epoch 4 and for Lucid GNU Emacs 19.8. -- Adrian Aichner mailto:adrian＠xemacs.org http://www.xemacs.org/
