transparent - or not?

[liunx]

Okay, so now I'm working on some transparency stuff - and for some reason it's not working too well. If you look at my page (<!-- m --><a class="postlink" href="http://www.siteprefect.com/ecb/newsite">http://www.siteprefect.com/ecb/newsite</a><!-- m -->) the box on the left (main) is transparent okay, but the box on the right (news) isn't. Why's that?

the relevant bits from my stylesheet are:

.news { margin: 10px 10px 10px 55% ;
width: auto ;
border: 1px solid #C00000;
background: #DDDDDD ;
-moz-opacity:.95;
filter:alpha(opacity=95);

}

.main{ width:50% ;
float: left ;
border: 1px solid #C00000 ;
background : #DDDDDD ;
margin : 0px 10px 10px 5px;
-moz-opacity:.95;
filter:alpha(opacity=95);
}They are both transparent to me. I am using Mozilla FireFox.humm, yes it works okay on my netscape too. Must just be an IE thing. rats.
