This is very strange, earlier today IE started to underline all the text on our website. No updates have been made today and it all looks fine in Firefox, Chrome etc.

Also if the site is viewed over a secure connection it is fine!

Any ideas anyone? I've checked the validation of the XHTML and CSS and everything seems fine, any help greatly appreciated.
