So *that's* why I can't zoom certain images! You could certainly zoom this one with ⌘+ and ⌘-. So a visually impaired student might zoom it and get a different answer. As might one who unknowingly used a zoomed screen. The kid who showed me the problem (on a rather large screen) says you can read the EBook on an iPhone or a tablet. That's an order of magnitude uncertainty. --rwg
