This is what I see in the compressed CSS file:
#home .panel-col-last{width:49%;}
#home .panel-col-last .more-link{padding-right:2.4em;}
#header #site_name,#site_search,#logo{padding:0;}
div#search{margin:10px 20px 0 0;}
#menu-2,#menu{line-height:1.6em;}
#site_name h1{padding:12px 0 0 5px;}
#home .item-list ul li,
#home .item-list ul li{font-size:1em;}
body .forum-comment .links{float:none;}It looks like my comment with IE6/7 is not liked by the aggregator since I don't see the rule:
#logo a {
display: block;
padding: 10px 0 0 10px; /* reposition logo */
}I can confirm that my rules are being placed before the other stylesheet I mentioned in my comment above. You have got a couple of options here but the simplest would be to add a new stylesheet after the Color module one in template.php.
If you can leave CSS aggregation off until after we've made sure everything is working perfectly that would be best.
