I have an interactive video with overlay slides. I published the eLearning with a table of contents and it has "Self Paced" checked. When I view the eLearning at the overlay slide portion, I close it. Then I reopen the eLearning (to see if it picks up where I left off) and I get the message in the browser that says "do you want to continue where you stopped." I click YES, and then the eLearning starts AFTER the interactive video. Shouldn't the eLearning pick up where I left off at the overlay slide? It's not, it's completely bypassing the interactive video when I restart the eLearning if I close the eLearning at the overlay slide.
Overlay slides are not on the same level as normal slides, they become part of the video slide. They don't show up in the TOC, will not be used for its bookmarking feature to which you refer. You could log a feature request.
I prefer to add a menu to the Interactive video slide which offers the possibility to jump to bookmarks in the video. It is pretty easy to do. Have a look at:
