Firefox not as good at using the TreeView control

[Clay_Shannon]

My site (www.knowitallsports.com (http://www.knowitallsports.com)) uses a TreeView control. In IE, this works fine; in Firefox, however, if I navigate away from the pageafter taking one of the quizzes(that is to say, if I browse to an external web site, such as using one of the links at the top of my page-to lulu or printfection, or to amazon), and then come back to my site/page, the TreeView is "dead"-it will not open.

Does anybody know why, or if Firefox is going to fix this, or have any insight on what's going on there?

Install Firebug in Firefox and use it to watch what is happening.https://addons.mozilla.org/en-US/firefox/addon/1843
