Question : CSS issue with hidden menu drop downs

Hi,

We're having an issue with the display of our drop downs in the top menu. In every browser, but Internet Explorer the drop down menu appear on top with the correct z-index. In IE, they're hidden behind other divs.

Any help would be greatly appreciated.
