Further digging appears to indicate that while the bug is unique to 
Windows, it is not unique to ActiveState's distribution of Python.  I 
did a fresh install of python.org's Windows build, and the bug is still 
present.  So the likeliest explanation is a bug in the underlying 
Microsoft libraries (something we've been bitten by on previous occasions).

I have also learned (since posting the original message in this thread) 
that although the Python XML SIG still describes PyXML as the premier 
path to full XML support in Python on the SIG's home page [1], this 
information is out of date, and lxml is now the preferred package for 
full-strength XML programming in Python.

Are there any plans for including this package with the ActiveState 
distribution at some point in the future?
