I just tried to the use thesaurus in OOo 2.3.0 Writer for the first time since I installed it, and the thesaurus is grayed out in the Tools->Languages->[grayed out] Thesaurus. This has only happened in one document I have (so far), but why there and not elsewhere I don't know. I have checked the document properties and there's nothing special about it - it's a "Word 2000/XP" .doc file, mime application type msword, and I have hundreds of those, all of which show the thesaurus (and it works). I checked the file ownership, and it wasn't "mine" so I chown'ed it to my user id, but there's still no thesaurus. I have modified the file numerous times under my user id, and still - no thesaurus.
What gives? mhr
