It's on 5.6.1.1 or something, the latest for the PW1. Darrenmcg noticed that on his, terms were selectable if they were on their own, but not if they were immediately followed by a punctuation mark. I made a change to correct that and it seemed to work on mine at least. Do none of the names work at all, even the ones that appear completely on their own with no other characters around them, eg " Graham "?
Edit: Darrenmcg tried it on the lastest Voyage firmware and was able to highlight most things:
