I have used this program for the past 6 months. This program is the greatest dictionary program I have ever used! If you want dictionary files, you just download them from the monash site. It is easy and it is free (after buying the dictionary) It looks up words forwards and backwords, the middle of the word, etc. in combinations (if you only know the 2nd kanji of a 2-kanji word), examples, and even multiple languages simultaneously. I am currently teach 2 foreign languages in Japan, and this program has been a life-saver for me! Some of my students have $300 (30,000yen) electronic dictionaries, but none of them can touch the simplicity of JEDict. Looking up kanji on JEDict is MUCH easier than online at the monash site. All in all, I don't see how anybody could give this program a bad review unless they either did not read the simple documentation, didn't utilize all of its features, or didn't download enough of the free dictionaries. It is a great program!
I give it 4 stars for stability, because sometimes wehen I can look up a kanji by radicals, it cannot find the kanji unless I include all the radicals (although this only happens one out of twenty or so times, it is annoying). Another annoying thing is that the free example dictionary sometimes has strange grammar, but that is also rare. Truly, this program is a gem among gems.
