Ah, that would explain it - thank you. That's a bit crap, innit? I'll send them some feedback.
Oh well, at least I got it working on my Palm by adding .txt to each filename using 'Name Those Files' - all in one go, including subfolders. Couple of seconds later and hey presto - folder sync using 'The Missing Sync' and it's all viewable via 'Documents To Go' on the Palm. Lovely!
