If you use Windows and are running Internet Explorer 6, I have a great deal of pity for you and three recommendations.
1) Hold the shift key and click the refresh button. Many of the horrible artifacts of my recent redesign will go away. You are still using a dead browser, however, so your problems run deeper than a simple shift-refresh. The next two points should help a little.
3) Look seriously at a Mac. It will look back, just as seriously.
