I have a collection of PNGs with drop shadows. They work great in IE7 and FF.
If I add filters in my stylesheets, such as
icon {
filter: alpha(opacity=10);}
-moz-opacity: .10;
opacity: .10;
then the PNG shadows all turn into solid black pixels (even If I say opacity 100).
Has anyone ever dealt with this issue? This is for an internal application for use by only a few dozen people, so I am not against hacks.
