Hello Edward Sudit,
In case you can only reproduce the problem in IE and in FF, Opera, Safari, etc., your page looks correct, then you have most probably hit one of the two Internet Explorer CSS limits. You can read more about the problem and the possible solutions in the following blogpost: http://blogs.telerik.com/kamenbundev/posts/10-05-03/internet_explorer_css_limits.aspx
In case this tip does not help you, please open a new support ticket and send me a running test project, that demonstrates the problem.
