To summarize : Desire a single blank page after TOC if TOC is on the recto page.
Situation: The TOC was just long enough to be reaching the bottom of the recto page, but not quite. The Chapter following would be "glued" to the TOC without a blank page between them., thus it would appear on the verso -- not ideal. Solution : Insert chapterprecis and type one line, then ctrl-enter and some spaces. I do this under all my chapters and this puts a line under the precis -- which also appears in the toc. This increases the toc size enough for it to break onto the next verso page. Suddenly -- the chapter behaves as expected and jumps to the recto page. In short : Increase the size of the toc by "padding" it some way. FWIW, \d
