How do I stop iCal from automatically adding alarms to new events? I am running iCal on Snow Leopard and, whenever I add a new all day event, two alarms are automatically added, but only after I save the event. There are no alarms present when I create the event; they only appear afterwards.

How do I stop this from happening?
There is an option in the preferences "General" tab, called "Add a default alarm to all new events and invitations". Maybe that's activated?
