Alta Vista's Babel Fish translator, via their webpage hardly ever works -- I only need Japanese English translations, and the site, no matter what page or words I send it, returns errors.
This doesn't happen under IE (but it's so old and buggy and non-unicode compliant) or on the PCs at local universities.
One of their main problems is their encoding (or poor handling of it)... and the website, at least on my fully multi-lingual machine, doesn't seem to handle drag and drops (or cut-and-paste) of Unicode, JIS, and Shift-JIS text.

Does this Widget solve these problems? (Apple's translator widget has several issues of it's own under Japanese kanji and kana).

You need Babelfish... as opposed to the translation widget that's already built in and very accurate?

Seems like too little, too late. Used to use Babelfish before widgets were around, but I've become familiar with (and happy with the results of) the built-in widget. Who needs more clutter for the same operation?
