I was typing an article on my Macbook Pro, and I got a phone call. I answered the phone, talked for maybe 2 minutes, and when I turned my attention back to my computer, I was confused to find some of my documents open that weren't before. Immediately, I saw the mouse moving on it's own, but not randomly - someone was actually using it, going through my files one by one. I couldn't grab control of the cursor back, so I just turned off the computer and am now typing this message on my other one. What the hell?! what is going on??
