ModalPopup and IE Styling?

Hey all, i am using a modalpopup extender and in firefox the styling is PERFECT. However, in IE, the modal is all black background, no opacity, and looks honestly terrible. Here is my CSS:

}.watermark {background: #FFAAFF;}.popupControl {background-color:#c2d0e0;position:absolute;visibility:hidden;border-style:solid;border-color: #6780b8;border-width:1px;}.modalBackground {background-color:#c2d0e0;filter:alpha(opacity=70);opacity:0.7;}.modalPopup {background-color:#c2d0e0;border-width:1px;border-style:solid;border-color:#6780b8;padding:3px;width:250px;}

Any ideas?

Acctually... nevermind... seems to make itself formatted properly when hosted by IIS... ;)
