The Mac DDD?

I’ve never really heard of this, so I’ve decided to call it the Mac Dimmed Dialog of Death. Happened to me for the first time today since I got my Mac, 14 months ago. I was always told that Mac OS X also crashes on occasion, never believed it till now.

I was working on an image in Photoshop with a dozen or so other applicaitons in the background (normal usage for me) when suddenly the screen becomes dark (it was translucent, I could still see my desktop in the background) with a dark gray dialog in the middle which says “You need to restart your computer. Please press the Power button for a few seconds”, in four languages.

On restarting I get some indecipherable report which I chose to send to Apple. Since then all has been working well. Hope it continues to!
