Under the slideshow and above the thumbnails is a section titled "Featured News from the Department & Community." This was made using multiple divs to get the colors and text lined up. I've noticed that the first time I go to the site in Opera, Chrome, or Firefox, the "Featured News from the Department & Community" text is randomly up above the welcome in the top left corner. However, when I refresh the page, it is the correct spot.
How do I correct this behavior?
Clear your cache
I loaded your site in FF, Chrome and Safari, albeit on a Mac and the Featured News showed up everytime underneath the slideshow. So maybe you need to clear the cache on your browsers.
However, you might want to look into the validation errors to completely clear up everything
