Tab Selection Fails to Direct

#1
I'm using a Web Site (www.photoshopuser.com), that I have used many times before with no problems. But recently, I noticed when I click on the tabs to go to another page, the Home Page that I was on, just gets redisplayed. I've done several Google searches but no luck. I even upgraded to IE9, and still no luck. Anyone have any thoughts on this?
