I have a friend whose Macbook Pro is behaving very strangely. Here is what she says: A few days ago, I started up my laptop and it's acting really weird! It's super slow and the mouse/arrow on the screen is moving by itself and clicking random buttons. I can't even get the cursor to stay in one place to type an email, so I'm actually on my roommates laptop right now. Do you have any ideas what this could be? It took me 20 minutes to try to send an email and it didn't work in the end. Any ideas?
