[Matplotlib-users] Re: WXAgg access violation

BTW, the embedding_in_wx4 example (among others) exhibits the same 
problem for me. I can always reproduce it by launching and resizing the 
window from small to large, without ever releasing the mouse button. 
This usually crashes within 10 resizes or so, but as with your 
description it's intermittent, it can take longer. This is with Windows 
XP, Python 2.3.4, matplotlib 0.61.0, wxPython 2.5.2.7. It was also 
present in the last matplotlib and wxPython releases at least. I seem to 
remember the plain wx frontend also being flaky under this kind of 
'abuse', but I can't seem to get that to break now.

I also notice that you get a shear effect on some of the resizes (where 
the plot is drawn as a parallelogram). That's reproducible by shrinking 
the plot very small, but also occasionally happens at other sizes. I 
can't be sure whether the size/aspect ratio of the window causes that.
