Hi bbleft
My own speculation is that you are using RoboHelp 6, no? In
that version, there is a pesky and difficult to reproduce bug that
will bite you when you work with content that has been imported.
What normally happens is that you interact with the Topic
Properties dialog in some way. After clicking the OK button to
commit the changes, WHAP! You see one or more of the ".Book"
messages. And the topics are missing.
So it's nothing you have done wrong or might change. It's a
RoboHelp HTML "feature" of version 6. There is, however, a way to
minimize or totally avoid this happening. I find that as long as I
make changes in other ways that avoid using the Topic Properties
dialog in any way, I safely sidestep the issue. So here are some
tips.
* If you need to change the Topic Title or the Topic File
Name, make the changes over in the Project Manager area on the
left. Keep in mind that you may click View > By Topic Title or
View > By File Name to list these in different ways.
* If you need to change which style sheet is being used, edit
the topic and use the Style Sheet Toolbar Icon to associate the
desired style sheet.
Hopefully something here was useful... Rick
