Trouble with IE

On this site http://bit.ly/a6zi1p when I click on a top menu item all the content in the next page moves to the left, only on IE, while it works fine on Chrome and Firefox. Any idea why this is happening? Thanks

Remove the comments from above the doctype as that will trip quirks mode and try again.


<!-- SINGLE PAGE TEMPLATE -->  

Add a z-index to your header that is higher than your slider.

/* header */
#header {
    position:relative;
    height:169px;
    width:996px;
    z-index:999;
}

thanks fixed!

Ok fixed that, on the home page the drop down menu goes beneath the banner, again only on IE, but not on the rest, how do I fix that? Thanks
