I have a macbook pro 2.4ghz core 2 duo w/ 4gb ram. Ever since I installed Leopard, the dock shutters and, randomly, the cpu goes to 100% usage and the fans go to max speed. My prior install of Leopard messed up my computer as well... Finder would lock up when I click on an icon (it would try to preview it and lock up). Does anyone have any advice to fix these problems? Thanks in advance.
