Something strange is happening. First, Address Book wouldn't launch. Then it bounced a couple of times in the dock. Then a question mark appeared on top of the icon on the dock. I dragged it out of my Applications folder and onto the desktop and it still won't launch. The strange thing is that all the contacts are still "in there" somewhere. When I push the mouse button and the screen comes up, I can look up my contacts on the Address Book Search and it works.

It all started today when I put a contact into my iPod Touch and then it synched. I even tried repairing disc permissions, checked for a bad font, and it still isn't working and now the icon has changed to a pencil/paintbrush/ruler icon picture (instead of the normal brown address book).

Any ideas?
