I am trying to create an image that stays in one place no matter how large the window is. This seems to work great in FF but when i open it in IE the image is not where i positioned it! Has anyone ever seen this? Thanks.

#apDiv4 {
    position:relative;
    left:370px;
    top:328px;
    width:154px;
    height:130px;
    z-index:1;
    clip: rect(auto,auto,auto,0px);
    margin-left: auto;
    margin-right: auto;
}
