Hi Moranis
In addition to what Leon offered up, I've noticed that
RoboHelp was eating (dropping) one of my own favorite meta tags
that I use quite often. My tag was one used to redirect. And I
later discovered that if I took care to place the tag lower in the
list of meta tags, it left it intact. So now I ensure that when I
add it, it's the last one in the list. Since doing this, RoboHelp
seems to leave it alone.
Note that it may not need to actually be last, but certainly
it was a problem if it was among the first three or four.
Not sure if this will help in your situation, but it may be
worth looking at.
Sincerely... Rick
