the problem with 'keep with next' is that #2 heading numbering doesn't start again after an intervening #1 heading, etc. - the result is I, A,B, II C, D, III, IV, E, F - so, it works for#1 headings - but it is unacceptable for #2 (or #3) headings - without it working, you can't make a correct Table of Contents
