Python/Codebox plugin performs weird

[Henrik Jeppesen]

For a longer periode Zim has been freezing when hitting a page that is using the codebox plugin (which in return requires the Python packages to be installed). Scrolling a little with the mouse seems to be a quick fix for this issue, so I didn't really see it as huge problem. Now, though, when I start Zim I get a little bug notification before it opens;

I am not sure what to do with the information - just a casual user - so I'll leave it here in hope that it will provide you with some value.
