Hi Folks,
I have a small tester here: http://kompsoft.de/test/eqdkp/ajax/calendarmonthcheck/demos/basic-views.html

if you click on the month Name in the Header, the monthpicker Shows up. All working. Only Thing currently not working is the previous and next button. These Buttons are disabled.

Any idea? Maybe fullcalendar intereferes with the Dates?
