Hello guys.

I'm using SU 2015 on my Macbook Pro and all of a sudden the middle mouse button on a cheap logitech mouse (which i don't know the model) stop working. Last time i worked on it everything was perfectly fine. Now i can't pan/orbit with using the MMB. Tried another cheap logitech mouse that i have here and i doesn't work either... Haven't changed anything, so i can't find out what's wrong. I'm not using any drivers.

Can anyone help me out with this?

Thanks in advance
