My Blog has an ongoing issue, #top is not working. It works fine in Google Chrome not sure about IE. Here is Screen Shot on My Blog: My Blog Link in Signature.
Don't agree if something works on chrome has to work on FF or other browser or vice-versa. I tried to point you to the right direction. Check out your website on IE8, Navigation is behind the content. It appears fine in chrome then isn't it should be fine on IE8 as you mentioned.
#top isnt always universally understood without having the proper id'ed #top at the top of the page. for an easier way you can just have it link to #, which will automatically move it to the top anyway, but thats just the very basic method so im not sure if it might work the way you want or not
