Can't post via notification center I have integrated both twitter and facebook account to my macbook-pro. I am getting notifications perfectly. The only problem I have is that I can't post via notification center. There're 2 buttons Click to post, one each for twitter and facebook, which used to work fine previously. Now suddenly they stopped responding. When I click on them nothing happens. I can see click animation(pushing of button), but it does nothing, no edit area to post my updates, nothing at all.  

How can I get the functionality back?
Solved following this guide. You simply have to kill the notification center process.
