HALcyon Daze
As I type, I am on hold with AppleCare. You know things have taken a turn for the worse when the procedure the technician suggested in a tone chock-full of confidence fails to produce the desired result and he then replies, "Huh," clearly confounded.

Update
Now several minutes later, the problem righted itself, at least for the nonce, as I was staring at the screen, prompting the technician to say, "That's weird." Huzzah, ladies and gentlemen, my HAL is a curiosity! Should the utterly mysterious problem recur, a deeper investigation shall be undertaken.
