I installed it on a new machine and logged into it, asked it to work on a certain file with same name as another file on my original machine, and somehow (I don't even understand how this has slipped past QA) it was using the content on the first machine instead of actually reading the file on the new machine.
Also, it once kept using an old version of a file I had updated by hand, despite me asking it several times to re-read the file.
Sounds like something not ready for serious use.
