[Tutor] IPython: trouble setting an editor

[Richard D. Moores]

64-bit Vista
Python 2.6 for IPython 0.10
I also have Python 2.7 and 3.1

I'd like to use the version of IDLE that comes with Python 2.6.
However, if I have the line

ipy_editors.idle()

in my ipy_user_conf.py,

And enter   edit,

What opens is the IDLE for Python 3.1.

So, in imitation of this line in ipy_user_conf.py:

#ipy_editors.scite('c:/opt/scite/scite.exe') ,

I swapped out the above line for

ipy_editors.idle("c:/Python26/Lib/idlelib/idle.pyw")

and now when I enter

ed fact.py,  or  just   ed ,    (fact.py is a script of mine that I
copied to C:Python26/Scripts)

the IDLE for Python 3.1 opens, all set to edit the SCRIPT
c:/Python26/Lib/idlelib/idle.pyw !

What's going on here? What do I have to do to use the Python 2.6
version of IDLE with IPython?

BTW entering   run fact.py    at the IPython prompt runs fact.py just fine.

Thanks,

Dick Moores
