Atahualpa Background image showing in all but IE

I was wondering if anyone can help me out with my problem: I have a background image that I want to use throughout all browsers but it doesn’t appear in IE… it works and looks great in the other browsers… anyone know why it doesn’t show in IE???

below is what I have in my atahualpa options>body, text & links>body style:

padding: 20px;
font-family: tahoma, arial, sans-serif;
font-size: 0.8em;
color: #666666;
background: #2F2411;
background: url(/wp-content/themes/atahualpa/images/siteBG7.png)repeat top left;

My theme version is 3.4.4 if that helps…
