Update (1/10): I have eliminated the most annoying problem and so will go back to the old them although there is still more work to be done. Let me know if you are encountering problems viewing anything because of the way it appears on IE7. I am aware of the problems with the right side of the page.

Because of the way that IE7 was affecting the appearance of the site, I have temporarily changed my theme to another theme that doesn't seem to have been affected as much. I am looking into this and will revert to the old theme as soon as I have a solution. Everything should work as before.
