It's a weird one, right? Through a ton of troubleshooting, I finally found the culprit. With QS running (yes, the latest beta version for 10.6), OSX will not go to screensaver or sleep the display. If I quit QS everything works fine.
Strange, yea? Anyone else having this issue? iMac 2.16ghz. Only peripherals attached are a few HDDs, Canon printer, EyeTV.
