I hope this isn't a duplicate thread. I searched and didn't come up with anything but I can't imagine I'm the only one. My Dual/GHz/DDR PowerMac (August production) will not wake from sleep after the Quicktime 6.1.1 update. The machine wakes but not the screen. It doesn this with either user loged in or at the login screen itself. I have to use key commands to tell the computer to shutdown (rather then doing a forced shutdown with the power key) then start the machine back up to use it if it goes to sleep. Anyone else having this problem?
