Using the Dark frameless skin, I have a problem where words are broken up like this in the topic navigation. If it were a standard topic I'd just shorten the headers rather than fuss, but this is a Troubleshooting page so it's tough to go much shorter without losing the reader. Is there a fix for this?
I can't tell from that image whether this is the In This Topic panel you are talking about.
Also which version of RoboHelp and are all updates applied?
