I should have said I am using the latest version of Chrome on Windows 7.
I was very frustrated while updating the calendar last night. Some recurring events were displayed twice. When I deleted an apparent duplicate, both of them disappeared. It seems like I have to double-check every change I make to the calendar to ensure it got posted correctly.
Recurring events seem to be a huge weakness. Especially problematic is trying to shift a recurring event into the future. I found I have to change the recurring event back to a single event with a new start date, save it, and then change it back to a recurring event. Otherwise, older occurrences don't get removed.
I think I may just give up on recurring events, and post everything as a single event. Single events are processed more quickly, without the spinner of death. Single events are also more flexible.
