At First I opened my MacBook Pro, the keyboard was non-responsive except for the mute button, and the brightness. Also, whenever I clicked it would automatically do a "secondary click." I am not an idiot, I only clicked w/ one finger, and it did this. I was somehow able to get into the internet and I continually pressed random things on the keyboard and got some working, and eventually spaces worked, but it wouldn't go away. That all happened after I shut it down, so I shut it down again. When I re-booted it, there was a thing bouncing around the screen. I am on a different computer, but the photo thing still won't work. Here is a description of the ''thing''. This ''thing'' had a circle in the middle, two dashes one under the other underneath the circle, the same exact thing but diagonally left at the top. Diagonally on the top right is a rectangle. The ''thing'' is white and in the background is a light blue color like the color when you are re-booting your computer after you shut it down. Hopefully someone can help! I know it would have helped to see a picture of the famous ''thing'', but sorry.
p.s. heres the kicker, i had been downloading some music off the internet, and that might have something to do w/ it.
