Minecraft Forums

So, about a month ago my minecraft got all messed up. Whenever I make an action on my mouse, (I have tried about 3 different mouses) my minecraft looks up. Note that this still happens even if I set the "place" and "dig" to keyboard keys instead of clicking, and it still does it! I have deleted and re-downloaded minecraft, but it still won't fix. I usually play in snapshots, but this still messed up on normal minecraft. Any Suggestions?
