iCal dummy events
After upgrading to ML, iCal repeatedly create dummy events on 12/31/69 at 6:00 PM. These events do not show up on the calendar, but a search of dummy shows hundreds of these events across all calendars that I use. This is problematic as it attempts to save events on calendars that are ready only resulting in errors. These events only appear on my calendar in ML. They are not present on my iOS systems (iPhone, iPad2). Any thoughts on why this is occurring and how to prevent it.
