I posted an errata sheet for my "Essentials of Macromedia Captivate" book today at http://www.iconlogic.com/Captivate.htm.
The main thing covered in the errata sheet is updates to the LMS lessons beginning on page 169. The software you use to upload SCOs changed so I updated the book and screen shots in the book to reflect the changes.
The PDF has notes detailing the changes.
