When I left click, the 3D cursor no longer moves anywhere; it instead stays stuck wherever it is in the scene. When I right click on anything, Blender zooms into whatever object is currently selected. I'm unable to select anything with the mouse; I can only select objects with keyboard shortcuts like 'A'. This happens with all new projects as well. I've tried exiting / reopening blender.
Is there some setting that would cause this? How do I undo this?
I'm currently using Blender 2.79
