Recently Word has been giving me an annoying little problem that I can't seem to figure out. I like to switch between several different documents for writing essays and such, and when I switch from one to the other it has a tendecy to hover a little window showing which page the document is on. As such:

The page number floats on top of whatever document I'm working on, and will not go away unless I quit Word. I find this quite annoying, as it gets in the way when I'm trying to work on essays and such.

Does anyone know what this is and if there is a way to fix it?
