When window is maximized in vertical directon only and a program wants to 
maximize it to horizontal direction only with one request it sends a 
request that toggles both vertical and horizontal maximization (vertical 
shall toggle on->off, horizontal - off->on).  Howere sawfish handles this 
situation incorrectly.  The window will go to the normal state. 
 
The problematic code is in lisp/sawfish/wm/state/wm-spec.jl: 
 
  (define (client-message-handler w type data) 
    (let ((handled t)) 
      (case type 
 
        ;;; ... 
 
	((_NET_WM_STATE) 
	 (when (windowp w) 
	   (let ((mode (cond ((eql (aref data 0) _NET_WM_STATE_REMOVE) 
'remove) 
			     ((eql (aref data 0) _NET_WM_STATE_ADD) 'add) 
			     ((eql (aref data 0) _NET_WM_STATE_TOGGLE) 
'toggle))) 
		 (atom1 (x-atom-name (aref data 1))) 
		 (atom2 (x-atom-name (aref data 2)))) 
	     (when (or (and (eq atom1 '_NET_WM_STATE_MAXIMIZED_VERT) 
			    (eq atom2 '_NET_WM_STATE_MAXIMIZED_HORZ)) 
		       (and (eq atom2 '_NET_WM_STATE_MAXIMIZED_VERT) 
			    (eq atom1 '_NET_WM_STATE_MAXIMIZED_HORZ))) 
	       (setq atom1 '_NET_WM_STATE_MAXIMIZED) 
	       (setq atom2 nil)) 
	     (when atom1 
	       (call-state-fun w atom1 mode)) 
	     (when atom2 
	       (call-state-fun w atom2 mode))))) 
 
The assumption that toggling both maximizations is the same as toggling 
full maximization is wrong.
