I made the mode work again with a feeble workaround in the function
zen-windowed-mode. I havent had enough experience with the workaround to
see if it always works yet.

;;; Copyright (C) 2008 Joakim Verona

;;License: GPL V3 or later
;;; Commentary:
;;
;;zen-mode is Emacs in fullscreen without toolbar and menubar
;;the function toggles between previous state of features and zen
;;
;;
;;I bind zen-mode to f11 like this:
;;;(global-set-key [f11] 'zen-mode)
;;
;;TODO:
;;
;;- Zen-master mode, like writeroom mode. (c-u m-x zen-mode), which
;; isn't customizable, it just turns all distractions off
;;
;;- There shouldnt just be a toogle, but a way to enter a specific
;; state, like scroll-bar-mode, probably with a numeric argument
;;
;;- Optionaly advice some modes like ERC so as not to interrupt while
;; in Zen, also dont Gnus while in Zen. You are supposed to concentrate :)
;;
;;- Currently zen isnt entered properly the 1st time, you have to try twice.
;;Note:
;; There are some problems in the Compiz WM, (and maybe other WM:s) regarding fullscreen:
;; When selecting another workspace temporarily and going back, Emacs
;; does not cover the wm panels as it should. This can be resolved with alt-tab a bit,
;; but its annoying. In Metacity it works well.
