I'm using RoboHelp X5 for Word to create HTML help. The
resulting CHM file contains some topics that appear in bold font.
This does not happen if I generate a WinHelp (HLP) file, nor is it
that way in the actual Word document.
Although you can generate a CHM file in RH for Word it is a
bit like creating a working model of the Titantic out of cardboard.
You can do it but you may not get the results you want. HTML Help
is better produced from the RoboHelp HTML application. If you
create a new project in that and then import either the .DOC or
preferably your .HLP file you should be able to convert the winhelp
project to html help.
