MY PB suddenly starting rapidly launching random apps until I can't control it anymore and can't even close them or get control of the reset menu. Reboot and same thing starts all over again. I have had this PB since last spring and this just started today. I haven't installed anything recent except the latest OS when it came out a week or so ago. Also now opening menus and sliding the icon dock up and down. Its like it's possessed. Any ideas?
