Ok, I was dreading upgrading my very stable Leopard system. As above in the subject title it now freezes/crashes after sleep mode since I upgraded to Snow Leopard last week. It sleeps than never wakes up. The screens are still on (screensaver) but the keyboard is dead, when I hit the caps key - no green light. Hard escape (command + option + esc) doesn't work. I have to hold the power button at the front to hard shut it down. Then press it again to power up. Did some googling and pulled up a couple of Apple Support threads: https://discussions.apple.com/thread/2304923?start=0&tstart=0 https://discussions.apple.com/thread/2306135?start=0&tstart=0 ..but these are like over a year old, thought SL would have all bugs fixed by now and I have updated to 10.6.8 - the latest version of SL Any ideas/tips/suggestions?
