emacs python mode problem

[Chris Fonnesbeck]

I've become a little frustrated with the python indenting in python
mode for emacs. I have tried setting the indent to 4 spaces both via
the configuration menu and by hand in my .emacs file:

'(setq-default py-indent-offset 4)

However, when editing python files, from time to time the indentation
falls back to 8 spaces. Anyone have an idea as to why this may be
happening?

TIA,
