hey everyone,
  I have an interactive python application that I am using pylab with.  I am
having a problem where I can only create a graph ONE time.  all other calls
to plot() and show() cause nothing to happen.

  I have used ipython -pylab as well, but the problem I am having with
ipython is that all the graphs will show up AFTER i close my interactive
shell.  Of course, ipython works interatively every time I 'plot' or 'show'
at the ipython command line.

  Is this a backend issue? Does anyone else have this problem?

issue can be summarized as such:
>>>from pylab import *
>>>def p():
  plot([1,2], [1,2])
  show()
>>>p() // works fine. graph pops up.
>>>p() //returns nothing, no graph shows up
>>>p() //same as above

I am on Debian Lenny, pylab .98.3-5
