Yeah, there's something funny with our handling of MappingNotifyEvent and 
refreshKeyboardMapping.  I haven't had time to look at this yet (and would 
appreciate help in this area!).

This should be fixed in the latest xmonad, make sure you've got this patch:

  * UPGRADE X11-Extras!  Manage iconified windows

Also, upgrade X11-extras.  This patch is key:
Fri Jun 29 20:58:31 CDT 2007  Spencer Janssen <sjanssen at cse.unl.edu>
  * changeProperty*: don't call fromIntegral, that just casts to bytes

Before the 'changeProperty' fix, xmonad would set garbage values for WM_STATE, 
which is used to identify iconified windows.  Because of the WM_STATE 
corruption, a simple mod-q restart won't be enough -- you'll have to restart 
your X server.  Please let us know whether this works for you.
