There is an alledged problem with synergy4wow that when the cursor leaves the screen of one comp, the char will move forward until the cursor comes back to the screen. Well, the problem doesn't lie with the software, but with num lock key. Both num locks have to be off one both computers for synergy4 wow to run correctly. I noticed that when I was having the problem, either my desktop or my laptop had the num lock key on.

I hope this helps everyone! Let me know if it did.
