Button That Won't Go Away!

[DeadZero]

I hope someone can help me with this.
I was in WinRAR and I clicked "WinRAR archiver" button, I don't remember
why, but whatever I did worked, so no problem, later I realized that it was
still there, like, the button "WinRAR archiver" was (and is) still there. It's only
half visible, so I can see through it but not fully. If I scroll or anything it stays
in the same spot, as if it was a sticker on my monitor.
The only way I've gotten rid of it is by playing League of Legends and going
full screen, because that just overlaps it somehow, when I go back to normal
it's still there.
I've tried turning off and on my monitor, and I used to get this problem all the
time, I would have to restart my computer to make it go away, I'd like to find
an easier solution...

EDIT:
I'm on Windows 7 using Google Chrome (not that GC should make a difference).

have you tried right-clicking your desktop and selecting refresh?

EDIT:
also you could try and see if its still in your process tab of task manager.

Did you restart your computer...?
The monitor doesn't have anything to do what goes on at the computer.

No, I haven't tried the refreshing thing.
I have checked that, and I couldn't find it.

I said that I restarted my computer in the first post.
I know, but it was worth a try.

Hmmm sounds like the programs glitching and won't shut down
try ctrl alt delete and finding the process for winrar and shutting that down manually if it's still there when the button gets stuck

(Sorry for such a late reply, if you've already solved this sorry)

Hmmm never mind, seems someone already suggested that
