[xmonad] xmonad stops responding even after removing loghook reference

Hey All, My xmonad installation on Ubuntu 9.10 i386 stops responding after a while. It's just like the faq entry here: http://www.haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#XMonad_... I've commented out references to logHook in my xmonad config file http://pastebin.com/f8622e8a Still, the same error is happening. Does anyone know if I'm doing something wrong? Thank you for your time. Sean Neilan
