Everytime I open iCal it repeatedly asks to add a new event
Every single time I open iCal on my Macbook, a dialog box opens asking to add a new event to my Home calendar. I hit cancel and the box keeps popping up. I have to hit cancel at least 10 times before it stops asking. Any ideas on how to make it stop?
