Re: [xmonad] Issue 389 in xmonad: Some applications are unresponsive after workspace switch

Comment #3 on issue 389 by meste...@gmail.com: Some applications are unresponsive after workspace switch http://code.google.com/p/xmonad/issues/detail?id=389 I got this behaviour too: switching from a workspace containing Firefox causes a CPU spike (Firefox consuming 101% CPU on a dual core); one can newer switch back to Firefox (workspace appears empty). Config : Ubuntu 10.04.3 LTS. It happened on XMonad 0.8, and updating to XMonad 0.9 did not improve things. The bug appeared last week, when things had been working perfectly for months. I believe it was triggered by an aptitude full-upgrade (GTK update ?).
