Walt, I downloaded 2.0 and created a sample document. The weird behavior does not repeat itself. The sample document's TOC acts as expected. Knock on wood.
But I open the same misbehaving document in 2.0 and the weirdness continues: NO STYLE master-page page numbers convert to HEADING 1 style when I apply the master-page to the interior pages, thus ruining the TOC where every page number is listed as a topic title (Heading 1) !
I guess the document is "corrupted," that mysterious thing that happens to some documents while everyone else is sleeping 🙂
I'll try to recreate the document and see what happens in 2.0.
Best regards, Ugur
