I have no real problem with the hashing (although I've heard some people state that it happens every time they start LimeWire, it hasn't happened to me - and I think it's a permissions problem). What really bugged me was the fact that nowhere (at least in the docs that I read) did it state that it was doing such a thing. Having some large files, I had no idea what was going on when I first installed. Luckily, (although frustratingly) I came up here and tried to ask... and tried to ask... and tried to ask.... but the server wasn't in the mood to accept my posts... After a significant amout of time, I looked at LimeWire again & 1 of the files had mysteriously appeared and it occurred to me what might be happening.
