MBP SR 2.2GHZ 15IN In the past week my MBP has started acting weird. It mostly happens while I am away from the computer. I return to hear a beeping noise. I quit all my apps one by one, but eventually I need to reboot. (( I have only noticed this noise before when I accidentally highlighted and tried to open too many files at once. As they continue to launch I would hear the beeping noise. )) Today it happened again, with a new behaviour.. Mac Mail was continually scrolling through my mailbox list. Safari was scrolling down the page to the end of the page. When I dragged the bar up it would scroll back down to the end as soon as I released it. And during this there is the beeping noise Is my trackpad starting to act up?
