IE6 PNG transparency fix with Backgroud positioned

Question

So I am using this to fix PNG transparency on background images in IE6

ul li a
{
    background-image: url('/NewSite/Content/Images/Sprite.png');
    background-repeat: no-repeat;
    background-position: 0 -48px;
    background-image: none;
    filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/NewSite/Content/Images/Sprite.png, sizingMethod='crop');
}

This works great, however I have run into a problem when trying to implement this with a sprite. The fix ignores the positioning and renders as if the position was top right.

Is there a way to force background position or a better way to do this. I would prefer to not use JavaScript or change to gifs.

Any help is appreciated!

Answer 1

AFAIK the only way to do what you want is with IEPNGFix
You will have to use JavaScript, but you can warp it under conditional comments, like i do.

<!--[if lt IE 7]>
    <link rel="stylesheet" href="css/ie6.css" type="text/css" />
    <script type="text/javascript" src="js/iepngfix_tilebg.js"></script>
<![endif]-->

Inside ie6.css

ul li a { behavior: url(iepngfix.htc); }
