I think I understood where is the problem. Maybe there is one database (in English) at the root of the software. What I want is to use a French one, it was possible with the previous versions, but not with TBS 3.2 as Jonathan Leger said in another place of the forum.
So even if I put a favorite or many, they won't be recognized.
I put though some new terms in the thesaurus I have (in French), I even tried to put some in a .txt file and imported it, still no progress.
The tab "word/phrase" does not recognize any word in French ! For what you suggest to do, it is not related.
That is to say, for the software save favorites, it need them to be on the list, except that I have no words recognized in my list, so I can not add any favorites at all !! Do I make myself clear

?
The problem is way to complex, we need to use a previous version, that is the only solution that can work now.
