Never mind, I just found a fix. I added a position:relative to my body tag.  I haven't tested in Opera but it seems to be good now on Ie 7.0 and Firefox 3.0. I just don't know how to explain...

 

BODY
{
    position:relative;
    margin: 0px auto;
    width: 900px;
    color: #999999;
    font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
    background-color: #666;
}
