Cabal Question, was: Re: [xmonad] New Layout: ThreeColumnsMiddle

Hy, a question to somebody with cabal-knowledge: Wich files should be added to the cabal-file? Is a new layout like this supposed to be added to the file? If yes this is missing in the patch. Thanks for anyone who can tell me the rule. On Fri, Jan 02, 2009 at 10:12:12AM +0100, Carsten Otto wrote:

Everytime I invoked or hid Scratchpad, it would leave a 'Maybe.fromJust: Nothing' line in .xsession-errors, and updatePointer would stop working.
