At least for Spanish translation, the "dictionary" is only semi-useful. The advantage is that you can ADD your own entries, as you discover their meanings (perhaps by looking up regionalisms, colloquialisms, slang and idioms at the Royal Academy's online dictionary at http://buscon.rae.es/diccionario/drae.htm ) With the exception of the Oxford Spanish Desk Dictionary (2nd Rev. Ed.), most of what passes for Spanish glossary in print hasn't been dusted off since the Fifties. Ultralingua is a tool I can't do without, but I won't update it until its word list improves dramatically.
