I own a MacBook Air. I've recently been having this problem where I'm not sure what I click, but after viewing a document it will stay at the top of my Finder window. I have no idea how to get rid of it (not trash it, I mean just take it off the window).
Here's a picture of the problem:
The name of the document that is at the top of my window (obviously) is highlighted. I just want to get rid of that.
