Hi. Sorry for the slow response. We "gurus" (ha!) are
employees like you and have to balance responding against our
workload. We do try to answer what we can when we can.
As to your specific problem, the way interhelp file links are
handled between HLP and CHM files is different. I have to admit to
not converting HLP files that had inter-help links so I may be off
the mark here. That said, I suspect your course of action will be
to go into each inter help file link and re-add it. You can do this
by double clicking on the link, clicking on the "Remote Topic"
option and selecting the CHM file to link to. You'll be asked to
copy the CHM into the project directory and then you can select the
correct topic.
I'm happy for someone else to chip in here if there is an
easier way.
