We're having some trouble getting our site to properly display using internet explorer. Everything is fine in Firefox and Chrome, but for some reason Internet Explorer overlaps our search bar with our navigation menu. You can see the correct version by opening up the below link with Firefox and the incorrect version using Internet Explorer.
We recently changed our theme to "Twenty Eleven 1.1" as our old theme wouldn't show up at all in internet explorer.
Any thoughts at all are welcome. Much thanks!
