    Prevent Body Scrolling

    One of my pet peeves with fixed or absolute positioned elements is the <body> scrolling while you scroll the the positioned element.  Have you ever tried scrolling a dialog and seeing the page scroll in the background?  Awful user experience, bordering on embarrassing.  Yikes.
