There is a major bug in the Tri-pane output format / ishWebHelp DITA-OT plug-in. RWS refuses to address it under [costly] paid support.
I recommend that any users who depend on this output for production deliverables immediately abandon it. It is unreliable.
Why RWS would deliver this output format with one [at least] major bug, and then evade any accountability by putting in the documentation that it is "for demo purposes only," is beyond my comprehension.
I would have thought RWS values its reputation as a leader in this space.
fixed typo
