Thank you Alex for your detailes reply.

Before switching to Python 3.1.2 I removed all my Python 2.6 packages
(python, pywin32, numpy, wxpython). However, the removal was not
complete since some files could not be removed. Additionally, I still
see my C:\python26 directory which is suposed not to exist any longer.

If I go to the Control Panel, I cannot see any of the above suposedly
removed programs as pending of removal, so I really do not know what
more to do. I was even thinking of removing the C:\python26 directory
with the Supr key, but I always heard that it is not a good idea, the
Registry could become inconsistent. Additionally, I have not found in
my Win7 system nay utility for fixing it, should it become corrupt.

Perhaps my questions concern a bit more the Operating system (windows)
than they do python, but since I am fond of python and I definitely
would like to become somehow proficient at it, I would like to solve
the problem that I have.

I would not like to take a lot of your time, but, do you have any
hints as to what I should do to 'tune' my PC?

Thank you very much for your help.
