A while back i fixed an issue i had on my website nav in IE7 at www.bluebean.org.uk
. basically the problem was that my social links disappeared when in IE7. I was told to remove the zoom;1 from #megaMenu and add it to the #access-container. This worked however it also messed around with my nav, so now when you hover over it the margin seems to disappear.
Hope you can help
