Ha! I did it! Finally downloaded a pt_BR (Brazilian Portuguese) hyphenation dictionary, installed it, and got it to working in OpenOffice. Maravilha!
Last year, after our USA trip, I spent two weeks crying my eyes out … from allergies to, I suppose, dust or other pollutants in the air. Most likely mildew. This year, no problem. I went for almost two weeks with clear eyes. Until recently. Now I’m getting it. May be from using some old books, or pulling sweaters out of the drawer for cold weather use. Hard to say. And hard to see. 🙂
