    My 23" ACD won't shut off when I put my mac-mini to sleep. I can't even get the power button or brightness buttons to work on the side of the display. I tried unplugging everything and zapped my PRAM and that didn't work. Seems like this just started after I updated to 10.5.8. It's really annoying since I have to physically unplug it from the 90w power supply.
