I can open up MC perfectly fine, and I can load a world with no trouble, but when I try to run around in the game, my view freaks out and start spinning rapidly. I believe that this is happening because the mouse does not snap back to the center cursor like when I run MC on a PC. I think that this is the problem because when I pause the game, my mouse is not in the center of the screen like it usually is, it is off in a corner of the screen. How can I fix this? Also is this happening because I am running Minecraft on a virtual machine (VMware) on my Mac?
