Does anyone else have a Ghost Window when using Firefox?

I have the latest Firefox installed, and I noticed when I'm using it, if I go into Expose, I can mouse over a hidden window that is a part of the firefox application.

Anybody else have this going on?
Know how to fix it?

I mean, it's not a huge problem, and has no effect on performance or anything, it's just kind of annoying.
