It's been a while since I worked on B.R.O.O.M., but I'm pretty sure it wasn't just a problem with curly quotes. I was able to get the code to work. The problem is that it's not so easy for people to cut-and-paste the code from the book to their Hype project.
I'm still thinking about this problem, but I haven't figured out a solution that I'm comfortable with. It's unfortunate that I haven't been able to solve this problem, but there are lots of free Hype templates now available.
For an app like Hype – currently a Mac exclusive app – the Mac App Store makes sense. Also, the Mac App Store is not as crowded, so a great app can be competitive there. But if Hype ever does go multiplatform, that's when FastSpring makes more sense.
