OS X: Mouse Wheel raises view

Solved by installing OS X 10.9 (Mavericks)

---

Scrolling around the hotbar was performing oddly.

When I scrolled with my mouse wheel or two fingers with my touchpad, I expected just the selected hotslot (on hotbar) would change.

When I scrolled with my mouse wheel or two fingers with my touchpad, not only did the hotslot change but also my view "scrolled" up and down or left and right if I scrolled left and right on my trackpad.

Steps to Reproduce:
1. Open a minecraft world
2. use a trackpad or mouse wheel to change the selected hotslot
