For the record, I've been running with my Firewall switched off altogether (blind faith in my own invincibility goes with the turf). Stief, as always, is more prudent.

And I may also have misunderstood your post. Stief correctly distinguishes between the number of files shown as Shared in the bottom left-hand corner of the display and the number of files shown in the central header. I had assumed the latter for Ultrapeer purposes whereas the former could be really excessive because you could just have offered all the files on your machine for sharing.

So, good catch Stief.
