Screen saver pops up randomly!?!?
I've had an issue with screen savers in Lion. When my MBP plugged into power the screen saver is set to turn on 22 minutes after no activity. I've noticed today several times the screen saver has popped up in significantly less time than 22 minutes. Once in tried to pop up in the middle of scrolling through a website.
