I was using " in the script instead of '. I changed them thinking it was the problem.

Somehow, I'm getting funky characters in the script, or whatever. I wrote up this test.py script in TextPad.

import poser                                                                                                                      print "Hello World"

Then I ran it. What I got was this:

ValueError: invalid x escape                                                                                        Hello World

So, something odd is going on. I wish I could figure out what. test.py is a very simple script, that should not give a error.
