IPython 0.8.2 svnr2445, Python 2.5.1(r251:54869),
matplotlib.__version__ = 0.90.1

This was with TkAgg. My Tkinter module says it's version is Rev. 50704.

So, I installed wxPython 2.6 from http://pythonmac.org/packages/py25-
fat/index.html and tried my luck with "backend : WXAgg" in
~/.matplotlib/.matplotlibrc , and this behaviour does not occur
(there is another small bug but it's far less annoying). So I'm
guessing it's specific to the TK-based backends. The question is,
does it happen on other platforms, or is it something to do with the
Mac (or MacPython) bindings to Tk, or is it some unexpected condition
that matplotlib isn't handling correctly. I think we can at least
rule out IPython being at fault.
With the WXAgg backend, issuing a Cmd+Q (quit) command while a plot
window is active will not only not close it but cause all further
plot-related commands to lock up the interpreter. However, you can
close plot windows and replot using the same figure # just fine using
WXAgg, while it would crash you in TkAgg.
I should probably also note that I'm using the Intel version of the
Superpack; the same issue might affect the PowerPC version, or it
