I have MobileMe syncing my iCal on my iPhone, my iMac and my MacBook Pro. All is fine except when I add a new event to the iCal on my MacBook Pro. It stays there for a few minutes, then disappears! It appears on the other two devices however but I can't get it to stay on the MacBook Pro iCal. I note that when I open the pane in System Preferences for MobileMe settings, on my iMac it includes a tick-box for Calendars but the same pane accessed from my MBPro does not include a tick-box for Calendars. Any thoughts?
