Did you move pages or did you cut n paste portions of text? Are the stories threaded together or separate?
In the Pages pane, I dragged the pages of each story to their new location. I turned on the text threads and can now see that, in doing so, I have ended up with a very confused text thread. As I said, everything is fine for exported a PDF for a print version of the book and the mobi file for the Kindle version, so it's not such a bad thing.
Is there a way to fix the threads without messing up the entire layout?
Thank you for introducing Story Splitter. I have a following it will be easier for me to copy and paste the stories into a new, blank template file
