Well, I've gotten this "green image" a couple of times, but a restart of photobooth always seems to work. I'll give the mic thing a try when I get home, thanks for the tip. Mine works great with 10.5.2, and as much as I'd prefer a matte screen on a laptop, this thing faces away from windows and picks up no glare. Overall, I love it and the aesthetics go well with the mac set up overall.
Update: got the mic working
