Re: Simple (?) I.E. and FireFox Problem
Always, always always validate first when you’re troubleshooting layout issues:
HTML
http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fwww.undercoverlawyer.com%2Fforum%2F
CSS
Fix issues that are described there. Some, like missing alt tags, are not going to have an impact on layout. I have found layout problems are almost always due to a div being closed to early or not at all.
