Hi Mike
I think most of us have experienced corrupted pages
I can't tell you exactly what causes them, but I have a gut feeling that mine occur when I copy, perhaps incorrectly, pages from one application to another.
All I can offer as
proof is that since I stopped copying pages, particularly by dragging them, the incidence of corrupted pages seems to have lessened. There may well be no technical reason for this, but there seems to have been a relation between copying and corruption.
Back (when v4 was released -- I think) I replaced copying
pages (not objects) with copying pages to the gallery, and then pasting them from the gallery. Since then, I have not had a corrupted page.
This is all supposition on my part and may not be supported by technical logic, but who cares? It works for me.
