Still very buggy....been trying to get paint tools to show up in display...so far have managed to lock up application several times but still no paint. After a long struggle got texture to show up, at least. Still studying manual and experimenting. The UV tools do work -- although they are poorly documented, of course. I still have hopes for this as a modeler and UV wrangler, but I'll agree this seems to be a "save often and get out of the application as soon as possible" tool.
