Well, I know that in Safari 3, 4 (didn't try 5 as I despise 4 and 5 and really despise 5) this site's header is fully visible at 1024x768. Same in FireFox 3. My guess is that you have preferences set for a larger resolution (thus a larger window). Click the green widget on the window's upper left, then resize to the full screen area and reload the site. That should do it. Safari shows the same behaviour if it is run at a high resolution, then run again at a lower resolution - it fails to resize the window properly and cuts things off, forcing you to manually downsize, then resize the window.
