Comment #1 on issue 408 by vogt.adam: WM_TAKE_FOCUS problem when using matlab gui for Xmonad 0.9.1, cpu amd64, Ubuntu 10.04 LTS system http://code.google.com/p/xmonad/issues/detail?id=408 Thanks for the detailed investigation. I can only help you try the patch on issue 177: You have to build xmonad yourself. You can install to your home directory (provided you've got cabal-install, darcs, and some -dev versions of some X libraries, which should be available from distro repos): darcs get http://code.haskell.org/xmonad cd xmonad darcs apply track-currently-processing-event.dpatch # the patch at issue 177 cabal install then for contrib (if you use it): darcs get http://code.haskell.org/XMonadContrib cd XMonadContrib cabal install
