Cursor position not locked when in games

Hi there!

Since a few days I've been experiencing some difficulties in some of the games that I like to play.
When in these games, when I move the cursor in game, I actually also move the cursor on the desktop.
So when I move it too far to the left, it shows up on my secondary monitor (left of the main monitor), and when I then click, I get sent back to the desktop and out of the game.

As you can imagine, this is very annoying and makes these games pretty much unplayable.
The games in which I've encountered this so far are: GTA IV, Dead Island and Skyrim (modded).

Any suggestions for fixing this?

I had this problem as well, if you have "Raptr" (think thats what its called)

from asus try turning that off, worked for me. unistalling it works even better.
