Evidently if you are using certain versions of Internet Explorer on certain operating systems, there is a problem with the page length and scrolling on the site. This is not a fault with the CSS on the site. It's a software glitch in IE. I already have over half a dozen hacks in my code to accomodate Internet Explorer. All other browsers such as Firefox, Netscape, Safari, etc. seem to view things fine. Internet Explorer 7 has been reported to fix the problem.
