Some people use Netscape Navigator and love it, others Internet Explorer. These are the Big Two. Some people don't know what they use, maybe they are on America Online. There is a new smaller browser called Opera and there is WebTV and a few others. Once again, this site is optimized for Internet Explorer.
All browsers interpret html code differently.
This browser seems to do the best. If you aren't viewing this site on a later version of Internet Explorer, you should. It looks so much better. And best of all, it's free. You can download it from Microsoft's website.
