I had the same problem about figures that freeze using IDLE and matplotlib but finally I manage to solve it with the help of Eric and also a bit of luck. Instead of using TkAgg I use WxAgg and it never hangs. I use Idle -n and in the matplotlibrc set Interactive I use all latest version of Numpy, scipy, matplotlib and wxPython2.8-win32-unicode-2.8.0.1-py25
