with eventcalender Version: 1.0 I see the imposibility to add an event on the December 31 2011.. all other dates are working just fine.
If I make one, it disapears when i refresh, and i never reaches the front-end website calendar
When I make one on the 30th of dec, al went well. When I move that one 1 box to the right, it disapears.....
