/*
    The following fixes png-transparency for IE6.  
    It is also necessary for png-transparency in IE7 & IE8 to avoid 'black halos' with the fade transition
    
    Since this method does not support CSS background-positioning, it is incompatible with CSS sprites.
    Colorbox preloads navigation hover classes to account for this.
    
    !! Important Note: AlphaImageLoader src paths are relative to the HTML document,
    while regular CSS background images are relative to the CSS document.

.cboxIE #cboxTopLeft{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderTopLeft.png, sizingMethod='scale');}
.cboxIE #cboxTopCenter{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderTopCenter.png, sizingMethod='scale');}
.cboxIE #cboxTopRight{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderTopRight.png, sizingMethod='scale');}
.cboxIE #cboxBottomLeft{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderBottomLeft.png, sizingMethod='scale');}
.cboxIE #cboxBottomCenter{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderBottomCenter.png, sizingMethod='scale');}
.cboxIE #cboxBottomRight{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderBottomRight.png, sizingMethod='scale');}
.cboxIE #cboxMiddleLeft{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderMiddleLeft.png, sizingMethod='scale');}
.cboxIE #cboxMiddleRight{background:transparent; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/Content/images/colorbox/internet_explorer/borderMiddleRight.png, sizingMethod='scale');}

I commented this stuff out as it had a negative impact on the look of the colorbox in IE8 when deployed into IIS.
So I'm not sure if it works as expected since the colorbox looked fine when using the ASP.Net Dev Server instead of IIS and 
it looked fine in FireFox when deployed to IIS but not IE... ? Bit strange - Shane Nall 21/09/2010
