ipython notebook + virtualenv works?

[ishi soichi]

Emacs24.2

Python 2.7.3

ipython 0.13.1

I am not sure if I should ask this question in this mailing list, but I'll give a shot.

Currently I am trying to set up python computing environment, which consists of ipython, numpy, and others.

There is an emacs interface for ipython, ipython-notebook mode, which looks cool.

I have followed the instruction in the homepage

http://tkf.github.com/emacs-ipython-notebook/

My question is 

What does the buffer look like when you did the following

1. Start IPython notebook server.
2. Hit M-x ein:notebooklist-open to open notebook list. This will open notebook list buffer.
3. In the notebook list buffer, you can open notebooks by hitting [Open] buttons. See notebook section for what you can do in the notebook buffer.

mine looks blank and if I try to type something, it says, "Text is read-only" in the minibuffer.

I have started ipython notebook server in virtualenv (actually all necessary components are in the virtualenv), 

Is that the problem?
