Mac Mini never goes to sleep

I'm thinking something running on my system is never allowing it show as "inactive".

My mac mini never goes to sleep, even though I have explicity enabled this option. In particular, the screen won't sleep, which is what I want most (less interested in the computer). I'm thinking something running on my system is never allowing it show as "inactive". Not sure what I installed...

Ideas?

My iMac had trouble falling asleep when iDVD was encoding a DVD. Someone on Apple suppor forums suggested that this may be caused by an application that for some reason won't hide. Check your running apps. If one of them won't hide, it may be also causing you Mini insomnia.
