I'm not sure if it's since I began using OSX Lion, but my iCal has stopped syncing with my iPhone. I didn't change any settings. More puzzling to me is that when I open MobileMe Preferences, "Calendars" was checked to sync, but then "Calendars" vanished entirely from the list of options before my eyes . A couple times it happened before I could click "sync" from Preferences, the last time I pressed "sync" and while syncing, it disappeared. Any ideas?
