Thanks so much for your efforts here, I downloaded the dictionary files and added them to my Bebook. (BeBook 1 aka Hanlin V3) What I have found though is that while the dictionary "works" there is something decidedly odd about it.
I have searched for two words - LAUGH and URCHIN, both of which appear in the GCIDE I have in Mobipocket form.
On the BeBook LAUGH gives me an entry for "Laughing Bird" and no ability to step forward or backward.
URCHIN returns no matches.
Examining the .index file both words appear in it so I would expect to be able to display an entry for both.
I haven't done extensive checks but it seems like something is broken
