Is this always, or just part of the time? My G5 2x2 doesn't like to go to sleep on its own a lot of the time. I seem to have less problems after rebooting, but even then I still sometimes have problems. I think part of the problem is one or more of the applications that I often run. Or a WAG would be that it might be memory related, as after it's been running for a while I have little or no free memory. Zane
