I have used Adobe products for at least 17 years and have always learned the programs using Classroom in a Book. I have worked through every page of every lesson of this book. The product is substandard, but I believe it is not the author's fault. To begin with, he created this book and its lesson projects using a preliminary version of the software, and there are many examples of unexpected changes. For example, on page 245, unlike the illustration, "scene selection" does not appear until you have placed menu markers, which you either have to find on your own, or read ahead a few pages and work backward. Organizer is deeply flawed. It crashed literally dozens of times while I worked with chapters 1 and 4. I couldn't work Chapter 12 at all until I found the recommendation in an adjacent review that you need to use msconfig to uncheck elementsautoanalyzer. The worst problem is that Adobe does not provide a distribution disc of the chapter Lessons. You have to download them from Peachpit.com in compressed format. Each Lesson is at least 200 MB. For me the 12 chapters of download took 4 hours. While you don't have to sit and watch, you have to check your computer every 15 minutes or so to save and download the next lesson. Then, after you extract the files, APE12 fails to open most but not all of the lessons. Working through the book took me at least double the normal time because I didn't have the lesson materials available. I believe Adobe excluded the distribution disc to save $0.25 and to prevent secondary users from using the book. Basically, they failed to deliver the purchased content to those who purchased the book. I learned APE12 using this book. I am glad I upgraded. But Adobe owes to everyone who purchased APE12 and this book an apology, a repaired version of Organizer, a revised copy of this book reflecting the program as it exists, and a distribution disc of the lessons. Shame on you, Adobe.
