What do you mean by "made a Save with the collection I'm working with?" That's what I'm trying to do. There's no "Save" button.
And can you please provide a full screen shot instead of cropping your screen shot? I do NOT see on my screen the "Create Saved Book" button that you've shown.
I have finally discovered the "Create Saved Book" button. It occurs after an image collection has been completed and the "Book Module" is first selected while that particular collection is open. I discovered this quite by accident!
Books I've already created do not exhibit the "Create Saved Book" button because "Create New Book" from the Book Menu automatically makes the new book a "Saved Book."
Problem solved! Button found! Thanks for the help.
