I was burning a cd and after it was done the cd wouldn't eject and gave me a beach ball. Then I couldn't force quit itunes. Next my track pad stopped working so I plugged in my mouse and it worked. I then unplugged the mouse and the track pad would move around but when I click on things in the dock, the menu would flash 2 times and not let me do anything. When I used spaces, it would flash all 4 spaces quick and my dock would come up. I then had to plug the mouse back in to turn off the cpu. Now it seems fine and the disc ejected. What should I do? I have a white macbook with all the up to date software. I repaired permissions the other day after I updated the OSX via software update. What now?
