zindex + jquery: How to make my menu appear over the jquery script?

[Rwar K?]

I'm trying to build a simple site but I'm just blocking on this weird bug (?) that puts my "hover" menu UNDER the jquery/iframe div.[url removed. thanks for your answers!]When the page opens, it's the first menu item on the top left. As you see, it appears under the images below and I have no clue how to fix this!Is it my CSS, DIVs of jquery that is the problem?Thanks
