Stan,
Your suggested changes have all been made and the Monitor only plays the first part of the timeline, gets to the first Chapter marker and quits. That happens with all buttons. I've attached a screenshot of the Chapter Playlists and the updated Project window. No matter what I do with the Chapter playlists . . . they all keep pointing to the same place and whatever I change it to, they all change at once. Next idea??
No matter what Playlist is selected in the Project window, the same 4 chapters appear in the Chapter Playlist and any change affects all of them. What have I got crosswired???
