The opacity will work in the latest version of IE, but for old versions, if you want it to work, you can go into your dpta.css template and change this:

.threadbit .icon {
	opacity:0.6;
}

.threadbit.new .icon {
	opacity:1;
}

to this:

.threadbit .icon {
	opacity:0.6;
	filter:alpha(opacity=60); 
}

.threadbit.new .icon {
	opacity:1;
	filter:alpha(opacity=100); 
}

I stopped writing code for old versions of IE. If the user doesn't want to (or can't upgrade to IE), and they also don't want to use a browser that works properly with CSS standards, then ultimately it's their choice.

That being said, if you (personally) want to support old versions of IE, that code will do it.
