I was having (I think) the same trouble, where the window would freeze if I took the focus off it or tried to drag it around, using Python 2.7 on Windows 7 with Matplotlib 1.3, and TKAgg backend. I had a call to time.sleep(1) in my main while loop, and when I replaced that with plt.pause(1), that fixed the problem. So, try and use matplotlib's pause function rather than time module sleep function, it worked for me.
