I started this thread and have since developed a workaround
(similar to jc@salient) which I have detailed in a two-page Word
document. The document also explains several RoboHelp defects
related to this problem (hint to any Adobe people who monitor this
forum).
This interface doesn't seem to allow attachments; so, if
anyone needs a copy, email me at shaun.mclaughlin@entrust.com and
ask for it. Please put Robohelp on the subject line.
If anyone adds refinements later, please share.
Regards
