I'm not quite sure what triggered it, I think it was the latest update to Crayon, but the mouse-over highlighting for Crayon isn't working as it should, and in fact the themes appear broken in general.
Here's a screenshot of the problem: http://jarrpa.net/uploads/2012/04/bad_highlighting.png
Here's a link to the page with the problem, so you can see what happens when you mouse-over stuff: http://jarrpa.net/2011/12/07/coding-speed-vs-legibility/
Any help is appreciated. Thanks!
