First off, a very nice piece of software, thanks for creating it. 


Now on to my specific problem.  I’m using the GD backend on Windows with Matplotlib 0.41.  If I set the dpi to over 60 the png file that gets generated is ‘empty’, it’s only 17 bytes long.  As soon as I drop he DPI to below 65 or so, I get the image file correctly.  This is with the simple_plot.py example.


Any help would be appreciated.
