Thanks for the replies.Ideally I would want there to be a table of contents or equivalent that would change dynamically based on whether the participant has accessed areas of the course. The participant would see the full contents of the course but would only be able to visit pages he or she has already been to, as well as the next page.I'm using Lectora Professional Publishing Suite 2007.I also should point out I'm fairly new at this, and it wasn't my idea to try to do something this complex! To make a long story short, my company was deciding between buying something off the shelf or developing our own material. We decided to develop our own material so we could include company-specific info and more/better learning activities, but my internal clients really liked the navigation of the off-the-shelf course. (The off-the-shelf course looks to be all Flash.)
