Copy button won't go away?

[Wolfy]

For some reason, the "Copy" button (Like, what you get when you right click after highlighting something) is stuck on my screen. I can't click it, nor can I get to go away. As soon as WoW gets done patching, I'm going to try restarting my computer to see if that fixes it.

Anyone else ever had this kind of problem?

Go to your desktop, try pressing Ctrl + R.

Should fix it, if not, randomness.
