Why don't you have any associations pointing to the launcher? Did you delete
them? If you uninstall and install the launcher, are they present?

It's not py's job to walk the path: the shell does that when you just type
"foo". It locates foo.py, and then invokes py because of file association - py
then checks the file for a shebang to decide which Python to dispatch it to.

I'm afraid I can't reproduce this. When I invoke a script with the default
py.ini, py runs it with Python 2. When I add a [defaults]python=3 entry, py 
correctly runs it with Python 3.

That's just test data, not a real "production" py.ini. I was testing out
something, which is why the spaces around = are every which way, and I never got
around to changing it. More importantly, those customised commands, while
perhaps useful for testing, are useless in everyday Python usage: perhaps -O,
-Werror, -E, -S etc. might be more useful. I'll take suggestions as to what
might be useful customised commands to ship as a default.
