Tooltips appearing behind content [IE7 issue]

[azadcreative]

The website is live here:

The javascript tooltips on the navigation appear on top of Steven Gerard and the ContentArea on all browsers except IE7?

I tried everything but nothing seems to work.

Any ideas?

This is only half an answer, I can get it to work in IE7 by adding a negative z-index and position: relative:-
<div class="container_10" style="z-index: -1; position: relative;">
(I don't know which stylesheet it's in so I put it in the markup)

and removing the html from the style (I don't know whether that has any other effect):-

/*html,*/ body {
font-family: Verdana, Geneva, sans-serif;
background: url(images/background.png) top left repeat-x;
}

so that's a start.
