Problem with page-up; in two-page view, pages start switching from left to right, then page-up stops working, get caught in a loop
In the two-page view mode, around pages 10-11 in a multi-page document [more than 150 pages], when I page-up the pages switch from odd-on-left to odd-on-right, and then, soon, page up stops working. first it starts to act like arrow-up, and then I get
caught in a loop and get nowhere.
This happened after I added some sections for meta-data before the start of the document itself. To do this I had to first delete the TOC, create five or six next-page section breaks, and recreate the TOC.
This happened in an earlier long document, but then the phenomenon went away. I can't figure out what is causing it or what I might have done to fix it in the other document.
