Well i haven't really tested if it happens to the other sides, cause my alt-PC is on my right.. And it does work sometimes, and when it works.. It doesn't stop working. It's only when I have to reconnect my pcs via octopus that I run the risk of having it not work. It's one of those things where right when I connect I can tell whether or not it will work..

But based on that could it be something not initializing properly?

I'm not using the mouse drivers, since it obviously has the capability of working. It has worked. Something is just making it stick to that spot.

also, the bypass thing is a nice touch, thanks. When I hit it again though, I lose my mouse again. Like it just vanishes off my main-PC without me touching it.

Edit: Not sure if this is relevant but when it gets stuck on the alt PC, It's still receiving clicks and everything, it just wont move. I can right click on the spot where it's stuck, I just can't move it anywhere.

Edit AGAIN: Is it possible that it could be something as simple as a latency issue? My alt-PC is connected via wireless, and occasionally when I do have full mouse functionality, the cursor will lag quite a bit temporarily.
