the book is currently under review because we're planning to print it.
I think "too many mistakes and misprints" without examples is a little unfair, it's been proofed and mistakes do sneak through but the other couple of thousand people who bought it never mentioned anything.
It's "easy to correct them" on my computer but time consuming to replace files with the delivery system we use, and I only do it when there have been a few corrections to do.
I found the rest/ties error, perhaps Evgeny can enlighten me on some of the misprints, cos I just read through it and not seeing any more!!
