var leftNav = document.getElementById('IWS_WH_Elem_LeftNav'); leftNav.appendChild(document.getElementById('adLoader'));

I would imagine something is missing in the code. But it sits on my home page and in K-Meleon only. IE, Firefox and chrome don't show it. Any advice?

what page is that? local page? it's a javascript function but it doesn't seem complete.. i searched for adloader thingy and it appears to be some sort of consensual ad server.. might be you've downloaded it or you got infected by it from a not so nice website or in kmeleon's profile?
