Hey Nathan
Thanks so much for getting back to me - your advice helped a lot! I had way too many padding-bottoms and padding-tops on all of the header sections.. by removing these and putting all the padding into #navigation, all the spacing was uniform across all browsers.
So this leaves me now with two issues.. the smaller one concerns the overflow not being hidden on the horizontal image gallery on the home page in IE6..
The big issue though is that none of the image links are clickable in any version of IE.. the nav works fine, its just the two galleries that are playing up. i thought initially that it could be an issue with a .js file not being accepted by IE, but i dont think that is affecting anything.
I've spent some time googling this issue, and think it could possibly have something to do with Microsoft.AlphaImageLoader, or with z-index values, but after playing around with both, the issue remains.
Do you think you could shed some light on this issue?
Thanks again!
Steve
