You know how when you hover over an image or a link, or even a form box, you'll get a little box of text that appears? Well, I get an empty box. Not sure what might be blocking that text from showing up, but it's really annoying.
I'm running Firefox 3.5.2 on Windows XP.
Could it be an ad-block issue? Or a java issue? Any ideas on how to diagnose the issue? Or better yet, solve it?
