So the batteries on my wireless bluetooth mouse gave out, so I put in new ones. Although now, for some odd reason, I can use the mouse to click, but when I move it, the cursor doesn't move at all. I've shut off the mouse, and turned it back on. I've even turned my mac off, and switched the mouse on and off and it didn't help either. I also took out the batteries and tried it again. Any clue as to what's wrong?
