For the first time ever, I am finding that frame is, on its own, changing the application of master pages.
About once a day, I find that frame assigns the "first" master page to a page which most definitely did have "left/right" assigned to it. If I re-assign the correct master page to the 5 or so "mis-assigned" pages in this 60-page manual, I find that in a day or so, the master pages are changed again. This does not happen when I save and close the file and frame, and re-open. It appears to happen in the course of adding text and the manual page count growing. This is frame 7.2. Thanks for any help. best, Paul
