Example: I setup a new event. Click on new event to edit details. Put in new end dates, locations, etc. Click done. Everything looks fine. Then BLAM! iCal reverts it to it's state before I edited details. Undoes new end dates, locations, etc. I then have to go through and redo details again. Second time sticks. What gives?
Another example: trying to sort order of calendars. Drag a calendar down to bottom. All good. Then the f-ing thing goes back to it's original place.
These are new behaviors. These calendars and events I speak of are in iCloud, of course. I have iCloud set to Push. As I have always had it set. As I want it to be set.
