Okay, so basically my mouse works fine in any program except Minecraft. The left click and right click buttons work fine and looking side to side works fine but when I try to look up the camera goes down and vice versa. I've tried a few different solutions that I found but none work (mainly because it seems that nobody else has this problem.) Maybe it's super easy to fix but if it is, I must be missing something. Also, the mouse worked fine just barely a week ago, it just started acting up in the past few days.
