No track changes... However, I played around with this and
found that when I exported the content of the help file into a Word
document (which is how this document was created), it converted
certain text to one of two character styles (that it created - they
are not ones that I've seen/used before). The styles were "msodel",
which showed strikethrough and red, and "msoins", which showed in
black text with underline.
To fix this problem before Iimported the document, I opened
the Word document and modified these styles so that neither
contained strikethrough, red or underline. Then Imported it into
the Help Project.
All is well, but I still don't know why it did that in the
first place.
