Hello. I am trying to put together a site that uses 2 dd drop down panels. It works and looks great on Safari, Firefox, and Chrome, but for some reason it isn't functioning correctly on IE. The panels appear 'dropped down' when you open the page and will not close when you click on the tabs, instead it just flickers like maybe its trying, but they remain expanded. Is this a common problem? or did I screw something up somewhere?
