Thanks for getting back to me and for the clarification.

I understand the principle of 'swarming' but am dubious of the benefits of sharing a file when it is only partially downloaded.

Will it affect the network speed that greatly if I only share the finished download?

On the face of it I would have thought the fact that I am only sharing authenticated files outways the benefit of sharing partial downloads.

Anyway, I have checked what you suggested but have found nothing amiss. I download straight into 'My Documents', which is not shared; once the files have been verified I move them into 'My Music' (contained within My Documents), which is shared.

Anyway, it's an annoyance rather that a problem, so I wouldn't bother about it too much.

Regards.
