Hmmm, you might have something there on the plugged in/charging scenario. I'll have to test this further to see if that is the scenario that causes it to boot into Clockwork. Can this behavior be changed? Just wondering what the reason for this functionality would be.
Thanks!
I think it is a sort of "fail safe" to get you into clockwork if you are "bricked". What you might try is turning off and turning back on after being unplugged for a while. If it goes to recovery, start it back up and go into bootstrapper, click reboot recovery and ok to go to clockwork, then maybe that will reset whatever controls clockwork.
