python-mode.el vs. ipython

[Neal Becker <ndbecker2@gmail.com>]

I've been using python.el with ipython as subprocess for ages (C-c C-p from 
python buffer).  I'm curious about python-mode.el, because it seems to offer 
more features (or at least, more features on menus).  But it doesn't seem 
that python-mode.el gets along with ipython.  If I try python-mode.el  and 
start an ipython interpreter, as soon as I type a few characters into the 
interpreter the screen splits and my cursor is moved into some some buffer 
/tmp/xyxxx with a bunch of random code (I forgot if it was elisp).
I have 
(setq      python-shell-interpreter-args "--simple-prompt -i")

Any ideas?
