Navigation flyout div won't show in IE

My css-driven navbar works fine in Firefox, but not in IE. I think it has something to do with the Flash movie it flys out on. My page is here. The very first menu item is "Customer Service" and it should have a flyout item of "Claim Forms." I have tried using the wmode=transparent in my Flash embed and 开发者_运维百科messed with z-index in my navbar elements, but nothing seems to work.

you can try to give z-index value to container of the menu (with position relative). And also flash must have wmode transparent.
