Input queue lock brocken!

[barkdoll at cattell.psych.upenn.edu]

	The message "Input queue lock broken!" appears haphazardly on
my IPC SunOS 4.1.1 while running OpenWindows 2.0.  The windowing
system subsequently becomes unresopnsive, although the mouse pointer
is still alive and I can open a SunView binary if I have it running
under OW.  Any idea what is happening to cause this?  Thanks.
