Possible install bug in Python 2.3b1? (Python 2.2 still in the registry)

How was it installed (e.g., PythonLabs installer, ActiveState installer,
something else)?

File extensions get associated by default; that's something you would have
had to go out of your way to stop.

Know where they came from?  That is, where they are in the registry?  Nobody
else has reported anything like this (AFAIK), so I'm afraid you're going to
have to dig into it, and more than you'd like <wink>.

The PythonLabs installers never alter your PATH -- never did, don't, and
never will.  If you want Python23 in your PATH, you have to put it there
yourself.  Don't know about other installers.

Maybe so.  I can't reproduce any problems uninstalling 2.2.2 or installing
2.3b1 here, so it's hard to discern a pattern.

Not a bit, but it was a good try <wink>.

> Please let me know if you need additional information.

By default I'm going to forget this, just because I don't have a problem
here I can reproduce, nor one that has been reported by others.  You may
wish to record your observations in a bug report on SourceForge, hoping that
someone else will hit the same kind of problem and add their clues.
