I think nobody replied because you have found out for
yourself how it works. RH for Word does lose the structure and RH
HTML does not have a WinHelp output.
RH does require the Headings to be Heading 1, 2 etc so any
variants will cause problems as you have found. Better to accept it
than fight it.
I've not tried it but I guess you could import into RH HTML
to get your CHM, then create a printed output and import that into
RH for Word. I have a hunch though it will be more effort than is
acceptable.
Maybe your customers are not going to be early adopters of
Vista but surely they can all move to a CHM at least?
