The problem is that the overlay is supposed to darken the background underneath a pop-up dialog. The following is the code for the overlay:

        $('div#'+D_OVERLAY).css({
            position : 'fixed',
            bottom : 0,
            left : 0,  
            height : '100%',
            width : '100%',
            margin : 0,
            padding : 0,
            backgroundColor : '#000',
            opacity : .5,
            zIndex : 101,
            display : 'none'
        });

I can actually get Opera to show the background color at 50% opacity if I have the developer - web inspector open; otherwise the background appears transparent.

Does anyone know why this code is not working without the developer tool loaded?

Your assistance is greatly appreciated.
