Installation problem

I loaded matplotlib following the instructions in http://matplotlib.sourceforge.net/users/shell.html, including setting up the matplotlibrc file. But the xlabel command hangs.

In detail:

bash-3.2$ python -i

Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00) [MSC v.1500 32 bit (Intel)] on win32

Type “help”, “copyright”, “credits” or “license” for more information.

import pylab

from pylab import *

plot([1,2,1])

--------------------------------------displays plot------------------------------------

[<matplotlib.lines.Line2D object at 0x019DE430>]

xlabel(‘hi mom’)

--------------------------------------hangs forever-----------------------------------

I am running Python 2.6.1 in an Emacs shell buffer; the Python is running on Cygwin on Windows XP. I am not using ipython.

What am I doing wrong?

Thanks,
