It is not.  This mailing list is limited to topics related to Openwall
GNU/*/Linux, while in your question you're talking specifically about
running John the Ripper on Windows.  Although I do not think that the
problem you're running into is at all specific to the Windows build of
JtR, so I'll reply to the list this one time.  But please don't send
any further follow-ups to the list.

The proper author contact address for JtR is given inside the
downloadable tarballs/zips, and intentionally not given anywhere on
the web page for JtR.  I already receive too many questions on it, so
I insist that people at least download and try the thing for
themselves before e-mailing me.  Unfortunately, this policy has the
side effect that we receive questions on JtR to e-mail addresses
found on other pages of the Openwall site...

This looks correct.  It means that John has tried 126501 different
candidate passwords and is done with your wordlist.  The range shown
is what it was trying last (it does not try passwords one by one, but
rather in chunks of 128 or whatever it deems optimal for the algorithm
it uses for a particular hash type on a particular hardware platform).
Do not misinterpret this as the range for the entire session.

This is weird.  Either you're doing something wrong (and I'm quite
sure that you're, but I have no way to guess what exactly that might
be) or you've run into a bug in JtR (no, there's no known bug like
that in the version you're using).
