[xmonad] problem with neverwinter nights

Hello, I have a new problem. Neverwinter nights seem to have a problem with nwn. I use doFloat with it, and it starts correctly. But as soon as I change the active workspace, it screws up, and looks like this: http://jesgue.homelinux.org/other-files/xmonad-nwn.jpg Any idea? Thanks. -- Jesús Guerrero <i92guboj@terra.es>
