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!
