PyX on Windows

[Tom Longridge]

Hi,

I'm trying to use PyX to draw some diagrams with text in. I want to
change the font, so need to change the text mode from TeX to LaTeX.
However I get an error when I do so:

pyx.text.TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
  \documentclass{article}%
  \PyXInput{3}%
After parsing the return message from TeX, the following was left:
  *
  *(C:\Program Files\MiKTeX\tex\latex\base\article.cls
  Document Class: article 2004/02/16 v1.4f Standard LaTeX document
class
  (C:\Program Files\MiKTeX\tex\latex\base\size10.clo))

I'm using MikTek on Windows to run LaTeX; does anyone know if is this
likely to be the problem?

Many thanks,
Tom
