Hello XMonad I'm experiencing a sporadic problem with XMonad. Sometimes when I start a session, I am unable to move focus away from the first window that I open. I can launch further windows, but they do not get focus. I can send the focused window to a different workspace, in which case focus switches to another window (but I can't then switch focus away from that window). When I try to switch focus there is some flickering -- I think the red border disappears and then reappears again as though focus very briefly switches where I'm trying to send it and then goes back again. I haven't been able to see any pattern in when this does and doesn't happen. When it happens it starts immediately at the beginning of the session. Restarting XMonad doesn't fix the problem; nor does logging out and in again (I guess this is a big clue that there's something pretty fundamentally wrong). On restarting my box I seem to get a 50/50 chance that it will happen. I'm running Ubuntu 10.04, using XMonad from the standard package repo. I'm conscious that this is a rather unhelpful bug report. Can you give me any clues what I can do to get some more diagnostics for the problem when I experience it? Thanks -Ben
