i just realized that the kalender is kind of broken. in the taskbar it works fine, but when i click on on the clock/kalender in the taskbar the "popup" where you can see the clock and the kalender for november pops up for like 1 second than it closes itself. i can also see that all days 1 till 30 are white and only 18 (for today) is shown
i will do some test in the next days
