You mean you get to the >>> prompt?
And you type 2+2 you get this:

>>> 2+2

>>>

With just a newline between your input and the next >>> prompt?

I'm not surprised it doesn't work, that should have python trying to start
executing a folder. But....

I get a very different message:

C:\Documents and Settings\Alan Gauld>python (C:\Python31)
python: can't open file '(C:\Python31)': [Errno 22] Invalid argument

Nope, sorry, I don't understand how the 2.6 version works if
you are passing in a folder as you did for 3.1

Do you know how to cut n paste from a cmd window>
It would probably help if you pasted in the actuall sessions
into your mail.

HTH,
