I notice Peter's site has info on both X5 and 6 for this
problem. I'm using RH 7, and I tried linking to a PDF in a
second-level folder from a topic in the top level folder and from a
topic in a second-level folder. Both worked just fine, and the PDF
showed up in my baggage files in Project Manager. So Kathy, I
assume you're not using v7... If not, here's a plug for RH7, where
it seems the bug was fixed.
By the way, your link code suggests that the PDF is not
opening in a separate window, but in your topic pane. Is that
right? If that's the case (and it's not what you want), in the
Hyperlink dialog, select the "Display in frame" radio button and
"New Window" in the dropdown. That gives you the target="_blank" in
the code. Otherwise, the user has to use the TOC or the Back button
to get back to the help topic.
