I installed OS X Mountain Lion one month ago. Before, I had OS X Lion. Since yesterday, Calendar app window doesnt' show up. I have this app permantely opened. I had to force exit to close the app. I opened it several times with the same result. I checked iCloud calendar app in the web and everything is ok. Moreover, when I creat a new event in the calendar app of the iPad it shows perfectly up in the iCloud calendar app in the web.

I have just reinstalled OS X Mountain Lion and the problem persists. What else can I do?

iMac, OS X Mountain Lion (10.8.3)
