What happened to my login page after display sleep?
I'm not sure what happened but whenever my display goes to sleep and I click the trackpad to turn it back on, a dialog box shows up asking for my password. Prior to two days ago, when I woke the display the login screen would pop up with my user icon (just like the initial login screen, but without Guest), but now it's just the dialog box with a black screen. Anyone have any idea how this happened, or how to get it back to the way it was? I'm running OSX 10.8.4.
MacBook Pro, OS X Mountain Lion (10.8.4)
