I'm working on a slider (alternative to Slidedeck) is fine in all browsers - except IE9. The clickable area on the tabs is only about 40px tall, and sits at the top of the tab. I need the whole tab to be clickable, as it is across the other browsers.

I've tried messing with the CSS with no luck, and with the dtTop variables specifeid for IE, but I can't seem to expand the clickable area. I really don't know much about Jquery or JavaScript...any help would be appreciated, please!
