After experiencing many spinning beach balls in many applications on OS X 10.8.2 after a power outage, choose Restart. Logos 5 cancelled the Restart so could synchronize. Exit Now was greyed out. Ended up holding power button to force a power off.
Currently OS X 10.8.2 is sluggish; over a couple minutes to login. After another reboot to recovery partition, noticed a low disk warning.
Unexpected power loss with three Logos versions running may have some surprises since recovery partition has not (yet) booted up.
Keep Smiling
