I turned the firewall off and still have this error. I'm only using the loopback
anyway, not connecting remotely. I've got MySQL installed as well and don't have
any trouble opening the database on localhost. 

The shell is essentially disabled by this error. I can hit return and it goes to
a new line, but no prompt and I can't type anything in.  

Can anyone give me another clue as to a diagnostic I could do to better pinpoint
the problem? 

Another thing I tried is turning passive debugger on and that did not go well. I
got this unhandled exception when I hit return in the shell window:

I'm using PythonWin with no problem* and I've tested Qt and PyQt with no problem
so far. 

*I'd like to switch to Eric from PythonWin since Eric looks much better and I
can't debug gui code in PythonWin. Other than that PythonWin is working fine.

I can connect to a MySQL database with test code in C++/Qt or python/PyQt and I
can pop up label widgets and stuff. So it would appear that Qt and PyQt are
basically working. The Eric editor window seems to work fine, so I suppose
QScintilla is working. I tried some of the networking demos that come with Qt.
The loopback demo worked fine, as did the fortune client/server pair (using a
port) but the secure socket client crashed (OS put up a message saying it had
stopped working and would be shut down - typical Vista behavior). But the
fortune client server worked on port 50765 or some such, with no complaint from
the firewall (which I have subsequently turned on again). Does that narrow it
down at all?

Does anyone have relevant test code that might be helpful here in isolating the
problem? Or ideas of things to look at?
