Webware for Python

Hello all, 

An application we're developing on WebWare recently gave us an exception 
report that I can't seem to make much of; it looks like it was trying to get 
a session out of the memory store and couldn't find it, but there doesn't 
appear to be any of our code in the traceback, so I'm uncertain as to how it 
might have been caused.  This hasn't been a common problem, we're been 
through almost 2 months of testing before we saw it; but I'd like to run it 
by you experts to see if you have any input as to what I should be looking 
for.  The user was attempting to log out at the time. 

Thanks!
Chris Backas
