Hi Christopher,

This is the complete error log:

I definitely agree with you that this is a problem in ConfigParser, 
although this may be related to me using Python 2.2.3. I am going to 
install Python 2.4 this morning. I"ll let you know if that was the cause 
of my problems.

Thanks for you help,

Ben
