I recently published an AICC--compliant course in Captivate.
When I test the bookmarking ability (for students to stop in the
middle of a course and return where they left off), they is a 3-5
second delay where the first page of course shows, before it goes
to the bookmarked page. Also, when we bookmark a quiz page and
return to the course it just takes us to the beginning of the
course. And, the more we bookmark the course, the slower it is to
load when we access it the next time. Any tips would be greatly
