Ok, the dock was the key... When it is not docked, it still hangs.  I'm
not quite sure what output I can send you to help identify the issue,
but I'll give it some thought.  If you can think of anything that might
help, just let me know and I'll gladly send it along.

I did just see that you updated the patch, so I'll give that a shot and
see if it happens to resolve the issue.
