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

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

enter *python (c:\python31>)*,<br>

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

I get a very different message:<br>
<br>
C:\Documents and Settings\Alan Gauld>python (C:\Python31)<br>
python: can't open file '(C:\Python31)': [Errno 22] Invalid argument<div><br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
When i change the directory to c:\python26 and then enter it works ok.<br>
so can anyone tell me why this is happening?<br>
</blockquote>
<br></div>
Nope, sorry, I don't understand how the 2.6 version works if<br>
you are passing in a folder as you did for 3.1<br>
<br>
Do you know how to cut n paste from a cmd window><br>
It would probably help if you pasted in the actuall sessions<br>
into your mail.<br>
