No Mod Required

I'm kidding of course, my overall initial reaction is actually quite positive. For instance, I just saw it do this:

That promises good things in my future

Still, looking at my site, I'm presented with my very first Internet Explorer 8.0 Mystery ™

I use opacity to do the image replacement in my logo. As the following image shows, neither of the two techniques I'm familiar with to set opacity work in IE8:

The Internet Explorer filter:


#logo a {
filter:Alpha(opacity=0)
}


and the CSS3 Color Module color property:


#logo a {
opacity:0
}


both fail.

The Google tells me nothing and searching MSDN also turns up nothing, so I'm left to grapple with my first "what the?!?" of the IE8 Era…

Where oh where has my opacity gone?
Where on Earth can it be?

I'm going to keep at it, since I do use opacity often enough to turn this into an official "issue" for me. To that point, if anyone out there has any idea what's up with opacity and IE8, I'd love to hear about it.
