I'm not using any pointer warping. I'm afraid I haven't tried turning
off focusFollowsMouse yet -- I'll try that now.

I have discovered a few more things about this.
* It sometimes starts happening in the middle of a session.
* I can make the problem go away by using the mouse to
   switch focus.
* I can sometimes make the problem go away by pushing
   the offending window to another workspace and then
   going and getting it back again.

Is there any way to get XMonad to spit out any logging?
