Stewart — it’s even worse than you described. I don’t even know how many calendar apps that I have, but all of this quarreling among them causes calendar events to be deleted randomly from some or all of my calendars. Last year, I missed 3 doctors appointments and 3 business meetings because my gang of calendars ran off with the event and either hid it, destroyed it, or maybe put it on someone else’s calendar. It’s a mystery.
This is almost as bad as the hot mess that is bluetooth.
PS: How is it that a gadfly like you know about two-phase commit?
