In the matplotlibrc file, I changed the backend to WXAgg and interactive to True. import pylab def test(n): for i in range(n): f=pylab.figure(1) f.clf() a=f.add_axes([0.2, 0.2, 0.6, 0.6]) a.plot([1,2,3,4,5], 'ro') The error only happens for a large n. For example, test(10) works fine, but test(50) will cause the error. Also runing test(10) for a few times will also cause the error. Could anyone give me some help? Thanks.

No help here, just providing a data point for the devs. Under linux, with In [5]: wx.__version__ Out[5]: '2.8.4.0' In [6]: matplotlib.__version__ Out[6]: '0.91.1' I ran test(100) several times, no error.
