Hi,
IE has a problem determining document standards mode , obvious problem is:
(When you check page source)
<META name="y_key" content="0396b2f73093b654" />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd
">
<html xmlns="
www.w3.org/1999/xhtml
" xml:lang="en-gb" lang="en-gb" >
<head>
<base href="
www.tourdefrance2012.com/
" />
....
I don't know how you managed to put that there , remove that meta tag before <!DOCTYPE...
<META name="y_key"
