Default working directory

[vsoler]

I'm using Python 2.6.4 on Windows (Vista & 7)

I usually start Python by clicking on Start Menu the Python IDLE
(Python GUI).

However, if I want to save a new source *.py file, the default
directory proposed for saving is not the one that I want.

What can I do if I want that the change of default directory
permanently, that is, if I quit python and I reenter it, the default
is still the one I have chosen?

Thank you for your help.
