I turned on my computer earlier this evening and found that my Dock no longer appears. killall dock says there are no processes running. Finder keeps randomly relaunching. System Preferences crashes. Restarting does nothing Help! I installed iTunes 8, QuickTime 7.5.5 and Front Row 2.1.6 today and was playing Spore with a Mail window open the last time I shut down. Please, any ideas?
