Stefan: I tried using a template containing Autotext for entering captions, and also for generating tables of figures. It worked beautifully. No missing figures or tables in the TOF or in the cross-reference dialog box. And no "confusion" about which captions were for the body of the document and which were for the appendix.

Before pasting a problematic document into the template, however, I made a change and resaved it -- this means it was saved with SP3 on Office. Not sure whether this or the Autotext solved the problem, but it seems solved.

I didn't see where I could mark the post as solved, but I did rate your suggestion as Excellent. Thank you thank you!
