I use this software in its original form and advanced Mac for several years. In my version, it has no correction function; but whether you are a user of the common language, or writer, poet, student or teacher, I believe you will be surprised at the quality of its products and its ease of use, with OS 9 Classic and even with MAC OS X. Its use saves valuable time; his writing is also a rich culture (references, sinonymes, quotes) and a rare intellectual honesty. One objection certain words and expressions a little "waste" found in the Littré (eg a roger-bontemps), are not included in the dictionary it. But at home, he remains constantly on my "dekstop" and its alias in my dock.
