Split from this thread.
I have a similar issue. When major-minor versioning where only people with write access can see the draft documents is enabled, it seems that the synchronised folders are read-only, even for people with write access. If you open the document in Word, you get the same effect. Thus, that setting is not very useful and rather defeats the object, doesn't it? The only solution is to save the document elsewhere and then upload it. Is this really what was wanted?
