z-index problem in IE6

I have been struggling with a z-index problem in IE6 for quite some time now. I require part of the 'header' portion in my website to open up (usin开发者_JAVA百科g jQuery), and cover a portion of the 'content' section which comes after it. The thing works like a charm on all the browsers I've tested it on (Firefox, Chrome, Opera), but IE6 instead pushes down the content section, which is not what I want.

The website itself is here

I have done extensive research both here on SO and thro Google but all the workarounds I've found don't work for my case. Please help.

hi add this code specially for IE6 in class

    .imageflow .scrollbar {
    border-bottom:1px solid #b3b3b3;
    position:relative; 
    visibility:hidden;
    z-index:10002;
    _z-index:10002;
    _top:-10px;
    height:1px;
}
