So... I'm in a quite room with a bunch of people and booted into my GM Lion partition. With speakers wide open, the youtube video I had been watching yesterday started screaming at everyone. The mute button would've worked had I not stepped away during startup. (Thank god it was youtube. ) If there's one thing I hope 10.7.1 fixes is that damn check box on the shutdown screen that will prevent this. I want it to remember my last choice.
