Safari does not display my background-image from my CSS

I am creating a web site in which I want an image to be seen in the backgound with the text "floating" over it. The code is listed below.

/* CSS Document */

a{text-decoration:none}

body {
background-image:url(images3/greywolf1.jpg);
background-attachment:fixed;
background-position:top right;
background-repeat:no-repeat;
height:100%;
}

The image can be seen in IE, Netscape and Firefox but not in Safari. Is there a trick to this for Safari or does Safari not support this?

You can view the current page I am working on at:
