Turn off Lion's ical automatically set alarms?
I just upgraded to Lion and have been fine tuning ical. When I add a new event to one particular calendar, two alerts are automatically set (email and message). When I turn them off, shut the window and reopen the event, the alerts are back. How can I get the alarms to stay off and how can I set it so the default is for "none" in the alarm pull-down? Other calendars are working okay in this respect. I feel like there is a gremlin playing with my mind!
