Slydude,
Thanks for answering. I am a 20+ year programmer, but in Windows. Here are your answers:
1. I am pretty sure it goes into sleep mode. I am a newbie so I'm not certain.
2. I'm guessing it's about 10 minutes. I haven't timed it.
3. Yes, there are programs running. Mail is one. It is not always the same ones.
4. No, is does not happen when I am working
It acts like it is intentional, but I can't seem to find the place in system preferences where I can change this. It didn't use to do this so it's probably something I did. Thanks for the help. Btw I bought CCC.
