There have been a lot of recent Handcent changes. I installed it the other day, knowing that if I didn't throttle back the notifications, it would power-hog some. So - early this morning I finally configured the thing per usual (I don't need lots of pop-ups and notifications). And... while running a process monitor, the little beast seemed to have a heartbeat - 5~8 seconds of little cpu activity then 5~8 seconds (or more) of about 20% cpu utilization... back and forth like clockwork. I did a soft reset (restart from power menu) and this seems to have quieted it down, but will continue to monitor. Suggest others into process monitoring do likewise.
