On my MBA running Mavericks, with a password protected screen saver, all works fine unless I press a key or use the trackpad just as the screen saver begins to kick in. In that case, the screen goes blank and fails to wake or sleep. The keyboard appears responsive - the caps lock key light responds to key presses.
Not sure how to troubleshoot this - any help would be appreciated!
