This partially but not completely correct, but it is admittedly
confusing. Make sure you have read
http://matplotlib.sourceforge.net/interactive.html and
http://matplotlib.sourceforge.net/faq.html#SHOW . As emphasized in
the FAQ
IMPORTANT: show should called at most once per script and it should
be the last line of your script. At that point, the GUI takes
control of the interpreter. If you want to force a figure draw, use
draw instead.
If you are issuing plot commands from idle, you need interactive :
True, you should not use show, and if you want finer control of when
the plot pops up and it drawn, use the commands ion, ioff and draw, as
explained on the interactive.html link.
Hope this helps -- if you still encounter problems please let us know
because it is always possible there is a bug ....

I'm really busy this morning (like what else is new for any of us), but
I can confirm that there is a bug in 0.71. The root cause is that an
"extra" mainloop is now run by matplotlib in "Idle -n" which already has
a mainloop of its own.
I think the key to solving this class of problem is to detect the
presence of "freebe" mainloops to avoid running two mainloops while
ensuring that we run at least one. To do this, I'm hoping matplotlib
can ask Tkinter if a mainloop is running or not. The only alternative
that occurs to me is to detect the presence of particular shells and
maintain knowledge about the "freebe mainloop" status of each.
This morning, I tried to detect IDLE using "'idlelib.__main__' in
sys.modules.keys()" and was able to fix the current bug by suppressing
the mainloop and assuming that "Idle -n" is running and not "Idle". It
would be much better to detect the mainloop directly though.

Todd
