I use the ipad calendar all the time but I have just noticed that whenever I try and open march 2013 it closes the calendar and reverts to the front page. I have tried opening it from February by clicking the first day in march. I have tried turning the page, I have tried using the slider bar but the same thing happens. I have turned the ipad off and on again. Nothing works! Am I doomed for any appointments in march 2013?
