I'm trying to insert an image map into project A that links
to a topic in project B. Both projects are merged into the same
parent project. I want the linked topic to appear in a popup
window. I can make this work if the topic to which I'm linking is
within the same project...just not when it's in another project.
That is the way that image maps work. If you are using an
image map, the linked topic must reside inside the same project.
You could link to an external file by clicking the down arrow to
the left of the "Link To" field and selecting file, but this does
not allow you to display in a popup. Also if you are using CHM
files, the selected file would have to be the CHM which would open
with the default topic. If you were using Webhelp you could select
the individual HTM file.
