I am telling my friend that it is something in his new website that is causing this. He says no its not. In IE it display correctly. In Opera and Firefox it does not. HE has a banner in the upper left side of the page, then some text about signing up for membership etc etc in the upper right side. In Opera and Firefox these two run over each other. In IE is displays fine. Any ideas what is causing this?

It's pretty simple, Firefox and Opera comply with internet standards while Internet Explorer 6/7 does not. Simple.

If you want a solution to the problem, first you'll need to convince him to fix it, then you'll need to post the a link to the site so others will get a chance to look at the html code.
