I was wondering if anyone else is experiencing an issue in OSX 10.8.2 where they receive facebook notifications, but most of the time cant click on them to bring up Facebook.
I had that problem. I'm guessing you, like me, had the developer preview. If that's the case, delete Facebook and re-add it. Works fine for me now. Worth a try, at least.
It happens to me when I first open up the Notification Center and click on one. But if I click on another notification, it will open Facebook. A little strange.
