Having had to have a new HDrive after only 13mths for my new IMAC I have had to use migration assistant synchronising data from my airbook to my mac.

Since it has returned I have my calendar replicating every entry 10s of times and every time I make a move on the calendar it starts determining changes and each time the number increases.

Each time it does this the rollerball starts each time I move the mouse

Help - sooooo fed up with this excuse for a piece of software that clearly does not sit comfortably ie Microsoft and Apple...

Thanks
