In the bottom section of the attached page (Application Info, Workshops etc), the first tab is supposed to be highlighted when you first come to the page. This works fine. The problem comes when you click on other tabs. It works fine in FF, Opera, Safari, and Chrome. However, in Explorer that first tab continues to stay open as you click through the other tabs and they become highlighted. I have an bottom.css document that governs this section and iestyles.css that has helped solve some of the problems. This one remains a mystery to me. Any help is greatly appreciated.
