This is a good app. Its a must have for your apple menu. It has some flaws, like not telling you what dictionary the definitions are coming from when you search more then one source at a time. However there is something strange going on with this program. It is also released as Net DICTionary by the same guy, however he has gone to some lengths to keep them seperate (different web sites, slightly different names, but they are the same thing). Plus this other version is newer but was released before the other version. This other version is better, but carbonized. Very strange.
