The upload stat I am referring to is in the "Upload count" component of the Tools>Options>Statistics window.

Right now, I just opened LimeWire (Pro) with Zero slots, and it has Upload count figure of 1. Earlier today there was a count in the 1600s after I had been online for some time!! I can see the flow of searches, and occasionally see someone uploading -- however, I don't have that tab view open by default, so no idea when there's really activity in there.

TY for your reply.
