XEmacs 21.1.6 is the latest release I believe; it's what I use on
Solaris, but I haven't upgraded my Windows version in a while, so I'm
not sure if there's an installer for this version.  I'm sure you can
find a 21.1.something lying around, and I'd definitely recommend
upgrading.

You should also be using the latest python-mode.el, version 3.105.  I
don't think the XEmacs packages have been upgraded yet, but you can
download it from http://www.python.org/emacs/python-mode

Hmm, maybe you haven't saved your options?  I don't use the menus at
all, but IIRC you want Options->Syntax Highlighting->Automatic and
then save your options.

Personally, I never use tabs anymore, just spaces.  The latest
python-mode tries to be smart about setting the important variables
based on whether the guessed indentation level is equal to a
tab-width.  See the variable py-smart-indentation.

The problem comes, as you've noticed, with files that have an
inconsistent mixture of tabs and spaces.  My recommendation then is to 
set your tab-width to 4, untabify the buffer (C-x h M-x untabify RET), 
then save and revisit the buffer (so tab-width goes back to 8 and
py-smart-indentation can do it's thing).
    
Hope that helps,
