Dear All, I was wondering if I could ask you to clarify one issue. I am playing with IM layout for Skype. This is th relevant passage in my xmonad.hs chatLayout = avoidStruts $ withIM (1%6) rooster Full where rooster = And (ClassName "Skype") (Not (Role "ConversationsWindow")) I took ConversationsWindow from xprop. The problem is that opening a conversation window still gets opened in the sidebar and removes the rooster which goes to the main area? What I am doing wrong? I have seen a number of config files with the above line but for some reason this doesn't work on my machine. Opening other applications works ok. Any hints will be greatly appreciated, Robert -- Do you believe in the axiom of choice? http://en.wikipedia.org/wiki/Banach–Tarski_paradox
