title: Dropdown menu keeps disappearing & menu items covered by pic in IE7
body: <p>This problem only affects IE7. The hover effect works but when I attempt to hover over the sub-menu items, the menu suddenly disappears! Only, it's covered by the images in the header div. I've tried z-index and removing margin among other things but nothing works.</p>
