Due to both poor vocabulary and poor memory I often read with the resource in one panel and a dictionary in the other.
Today I was reading this passage...

Look up for 'jeu d'esprit' and 'rapprochement' produced no results!
Surprised by this I did a search of the dictionary (Collins English) only to find that both words were listed.

I am slightly interested in why 'Lookup' failed. Neither of the terms is arcane, gnostic, or obscure and, after all, had I been in almost any programme other than Logos the built in dictionary would have been most helpful.

I am hugely interested when this basic problem is to be fixed.
