Logo problems

small problem on my companies website

only appears to be happening in IE7

(when the security message loads just click ACCEPT, don’t worry it’s not saving a cookie to your machine or asking for any details…honest)

Fine in firefox, opera and IE6, not in IE7 though…

…any ideas :beam:
