Comment #1 on issue 263 by SpencerJanssen: PAP object entered http://code.google.com/p/xmonad/issues/detail?id=263 The most likely explanation is that you did not clean and reinstall contrib after updating the core. http://haskell.org/haskellwiki/Xmonad/Frequently_asked_questions#Help.21_xmo... Please let us know whether 'Setup {clean,configure,build,install}' for both xmonad and contrib fixes the issue. Don't forget to 'xmonad --recompile' as well. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
