Hmm, that's a strange one.  We've seen this once before

http://sourceforge.net/mailarchive/message.php?msg_id=3D8789882

and I can't remember what the solution was (the thread doesn't mention
it) but it was resolved.  I've CCd Gregory on this email to see if he
can remember, since he once saw the same problem .

Are you using the python from python.org?  Does it help if you remove
site-packages/matplotlib and then reinstall?  Please create this
simple test script

  import pylab
  pylab.plot([1,2,3])
  pylab.show()

and run it with

> c:\python24\python myscript.py --verbose-helpful

and paste in all the output and errors in your response after doing a
clean reinstall, as well as your OS information ....
