Query: I was very disappointed in that the CD-ROM wasn't up to par.

I too purchased this book in the hopes of learning Photoshop, but I was very disappointed that the CD-ROM did not have some of the files that the book called for. I did get some of the files from Macmillan Technical Support,but now that I'm working in chapter 11, I again find that I am missing files. I can say with all honesty that I would not recommend this book.
