You got the answer already, but I thought I'd just note that it's not just you. I see this semi-regularly at home where my laptop runs at 1600x1200 resolution (UXGA display). It seems to happen when the page has been hardcoded to a particular pixel width, effectively setting it for a particular resolution. I see the table tag here has width="773", so that would explain it -- it's set to display in a 773 pixel wide area. If you're running at a higher resolution than the code is set for, you'll usually see blank space. There's less blank space if you don't maximize the browser though, FWIW. I get about 3" of blank space on each side with the browser maximized, but about 1.5" on each side for the width I normally keep my browser at.
