Hi Tshering,
I think you are right when you say "... it did not care whether you already selected a different language in the search you did before."

.
Indeed, I use a french dictionnary and at the first search all is ok, but at the 2nd I can see that it tries to open a translation dictionnary (that is not installed and I don't want to find a translation, only a definition) !
So we have identified a bug : the default dictionnary is not maintained during the 2nd search...
Is it just the result of a bad setting or a real bug

???
Developpers you've got a new challenge
