I used to play ADOM when I have free time from work and other activities. I often read forums or chat and skype while playing. That's why I often have to minimize ADOM.

However ADOM does something even while minimized, one of my processor core is always fully occupied by ADOM!

This drains my laptop battery pretty fast, forces fan to work (usually my laptop can be completely silent) and sometimes even leads to overheating.
It's fine if NotEye requires all processor capabilities during the game but why these activities can't be suspended while ADOM is minimized?

For now most of the time I have to save and quit ADOM if need just to switch.

AFAIK this is happening for all recent versions with NotEye (both normal and Steam). I'm using Windows 7.
