Java APIs

Last year, I started having a problem loading a particular Web site page that I'd always been able to get before. Everything loads except a graphic box with text that rotates in one corner. There is just blank space on the page where it should be.

I was advised that this was probably a JAVA issue. I removed the Java application from my computer and reinstalled, but the problem persists. Any ideas? I'm using Windows XP on a desktop. It's possible that other Web sites aren't loading correctly, but I wouldn't know it. The site continues to show up properly on my laptop.
