With InDesign CS6 I cannot re-work a table in a file created with InDesign CS5.5. The half of the table disappears when I try. Any idea why?
A screen shot would help, but it sounds like the ext is going into overset.
When you open a legacy file in a newer version the text does not recompose using the new text engine until you interact with it in some way, but then it recomposes using the text rules of the current version and reflow is normal, but often results in changes to line endings which can cause oversets in tables or at chapter ends.
