I noticed the list there, and when I mouse over it I get the grab hand icon, but it won’t let me actually grab a section to move.
I am using Firefox 7.0.1 on Mac OSX Lion. I do notice a lot of errors in the error console. I am also using the theme zBench 1.3.1. Let me know if there is any other information you need that will help. I will try it in a couple of other themes and see if I can duplicate these errors, or if it’s the theme that’s causing the problem.
