iCal alerts show up by default despite preferences selected as "none"
I've set my iCal preferences NOT to set up alerts by default (both for "events" and "all day events") yet EVERY time I create a new event two default alerts are created, one email and the other message AND an email is sent immediately notifying me of a new event. This is incredibly annoying and I don't know what to do to fix it. My software is version 6.0 (1645). Help!!
