i'm also getting the hang... 10.5.2 w/all updates + SU 6.4.120

i notice it in two situations:

1. if there is an image imported. this causes a hang that requires a hard restart about every 15-20 min.
2. the beach ball hang... which i can't define with specific actions, but happens pretty frequently hanging for 10-60 seconds at a time.

anyone talk to google?

i just installed the thaw-up... thanks! i'll post my results...
