Ok, I've downloaded the Windows Mobile Power toys. Maybe there's
something useful in it.

Ah, I see.  Could the error window be made smaller and moveable so that
one could move it around to see the actual traceback?

I've attached it.  There are two issues with it:

First, you have to set the PC's IP address in the client.py script.
For me, 127.0.0.1 did *not* seem to work.

Second, you must start the server.py script on the PC before starting
the client.py script on the pocket device.  I was not able to start the
connection from the pocket device, although that would seem more logical.
