Thanks for the info. I'm bumping this up because it's been driving me nuts at home, but this past week it drove me nuts at work.
I was working at a Conference with a Nobel Peace Prize Laureate, and students were trying to show their presentations to the Laureate, and each of them ran in to problems with this scenario. I ended up taking out my personal laptop and running media for an hour so the kids could focus on their presentations.
But they were embarrassed, they felt bad, and their teachers were ticked off. Of course I got chewed out because I offered to help and was therefore only visible target for their frustration, but trying to explain this to people in the heat of the moment is terrible and I feel bad for all the people who have stood up to make a presentation, only to be flustered and freaked out by this implementation.
Is it as easy as mirroring for 5 minutes? Absolutely. For me. But kids & teachers don't know about this crap and they probably shouldn't have to. It should just work. Especially this. Imagine all the people this has screwed over as they stood in front of potentially thousands of people, only to have their tech fail them in an unreasonable way.
I needed to get that out there. It was bothering me. Not for me, I know how to work around it, but the kids... The kids man... ;)
Seriously. Is waiting for Mountain Lion all we can do? Because the people I'm talking about probably won't update right away anyways and therefore will be susceptible for an even longer period of time. Bummer.
