Ok, Google earth and ichat have both stopped working, probably others. It seems to have started when I did the last security update for my Intel macbook, with leopard a few days ago. Since then neither of those applications have worked. Not only that but when I start my computer, not only does it take much longer, but it starts up different then before. It starts with the normal white apple screen, then goes to a blue screen, then goes back to the apple screen with two mouse cursors. One that doesn't move and stuck in the upper left hand corner and the other that I can move around freely. After that it goes to my desktop and starts up. I have rebooted many times since the problem started, also I have tried deleting the PRAM, and repairing disk permissions, non have helped. Applications that I know still work are Firefox, Microsoft word, and itunes. Any help would be appreciated.
