It appears that your Internet Explorer has some kind of corruption in it. Depending on what version you have, (click help/about internet Explorer will tell you which) and go to Microsoft to update your version.
Better still, download the free Mozilla Firefox browser. It is as easy to use as IE and has a lot more features.

Leave the Beta version until later, it may have bugs in it. Just grab the 2.0 version and don't forget to let them know what you think of the browser after a month or so.
