Background Image won't center in IE 9

Question

I'm making a site with a background image on every page. The image is centered in Chrome, Safari, Firefox... But it won't center in IE 9 (not sure about the other versions of IE).

Here's the CSS:

#page {
    background-image: url(images/mountain2.jpg);
    text-align: center;
    margin-top: -50px;
    margin-right: auto;
    margin-left: auto;
    background-repeat: no-repeat;
    background-color: #6C86FF;
    width:1292;
    height:972;
}

(#page, is the div tag for the entire site.)

Help, is very much appreciated. =)

Answer 1

I think you should have a look at the specs concerning Background, especially the background-position property.

Answer 2

Have you tried setting background-position: center center;?
