I admin a WordPress site for my team at work. A couple months ago the category checkboxes in the Edit Post screen starting acting wonky in IE8 (most on my team use, unfortunately). When you click on the box, it doesn't show checked. If published the categories aren't saved to the post either. After Googling for some time, I couldn't find any similar issues. Anyone else run across this?. What's the resolution (besides making everybody use Firefox)?
