I just looked at the page source info for this site. It's dynamic; meaning it should resize according to your screen resolution. I'm more inclined to lean toward something in your browser is preventing it from properly rendering.
You said you use Internet Explorer. What version? MS is up to IE9 now.
I know from doing some websites IE6, 7 & 8 all have their little bugaboos that cause websites to render poorly. I'm doing a site right now for my gun club and I'm getting complaints (mostly from codgers) that they can't see certain things or the registration page won't come up. I nearly always tell them to upgrade their IE and the problems go away. Also clear out your cache.
Or better yet try Firefox or Google chrome.
We'll try to walk you through this. Hate to see anyone driven off by inability to see the screen.
