Alignment issue with header

Im sure this was looking fine before but now it isnt and i dont how to fix it. If you visit my site in FF first your notice my header is aligned fine.
If you now visit in IE your notice the logo is slightly above the menu.
I believe the CSS in question is below, but you may want to look at my whole stylesheet to get the bigger picture.

Code: Select all

top { background: #B82A2A; border:solid 0px black; height:95px; }
#logo {
 position:absolute;
 border:solid 0px blue;
 margin: 0px;
 padding-right:0px;
 left: 250px;
 top: -28px;
}
#logo img { padding: 25px 100px 25px 23px; }

If anyone can help that would be great. Thanks.

I'm not going to go searching for your code, when you can't be troubled to post it here, but I'll bet your problem is that IE measures absolutes from the top of the body, while FF measures absolutes from the top of the containing division.
