Oh yeah, I see your point. Fortunately, everyone around here knows better than to touch any of my systems, no matter what's on the screen. It could say "If you don't press OK in 30 seconds, the world will end", and they'd still take the time to come get me before pressing OK. I've got them trained well.

But the software I enconutered this weekend made me particularly angry because it didn't even have the OK button. It just rebooted the system after the percentage bar went to 100 percent.
