Hello, A couple of months ago there was a similar query to mine, but I didn't find an answer in my file. The question was about the German dictionary and mine is about the French, but might apply to others - I haven't checked.
I recently upgraded to 7.2. The installation is in English. I installed all the foreign dictionaries that I might need - right now French is the only one. I made sure the language value for all the paragraph tags is set to "fran?ais". I spell-checked a short document and the spell-checker was in US English, so of course, it kept coming up with errors that were not - quite useless. I couldn't find any help in the Adobe trouble-shooting questions. What did I miss? I don't remember having this problem in 7.0 or 6. Thanks, Ellen Lebelle
