Thanks jhowell! I've seen these. I have been able to use default and add extra dictionaries in languages like English, French, Spanish, Italian, without any problem. But for some reason support doesn't seem to extend to the Catalan dictionary. I've tried 3 dictionaries so far, including one that is specifically "designed for the Kindle" (whatever that means). I would have expected that one to work. If someone were willing to give it a try, here's the sample dictionary (available for free from amazon):

Does this dictionary get listed for you under Catalan? (or any other language for that matter)
Thanks!
