One error – should not happen – was caused by the new surface and a change of the checkbox control. The days in the templates were not selectable any more. Thank you David for that report! Most people just remove the app. Is it too cheap so that people do not care to report errors and wishes?
The other one was a very tiny bug – the hours of the clock were painted wrong for about 1 second at the full hour due to a bug in the animation calculation. Thanks, Sven.
