I am sorry if I am bothering or am asking stupid questions, but I really can not find it in the fvwm documentation (looking throught the manpages and the html documentation). I understand how PipeRead works (that I found in the manpages), but to make it rearrange my whole desktop, it needs to get a list of all windows and their geometry. I have seen $[w.width] (only in this list, where is it documentated), but that gives me only the current window. I need all windows ... Regards, Nathan
