I want to have on a page a centered image (only item in the page) and for that I linked an external CSS style sheet to the doent but the image shows centered in IE 5.2 for Mac and not in IE for Windows; it shows a 50 pixel down the top of the page.
Here is the code:

body {
background-color: 00CCFF;
left: 0%;
top: 50%;
position: absolute;
margin-left: 0px;
padding-left: 0px;
