Hi guys

I'm on Mac OSX, but had similar lockup problems that took months to sort out. The main culprit turned out to be the p2p throttling software the ISP was using (CISCO NBAR--freely supplied). It allowed leaf connections and downloads, but made uploading very difficult and Ultrapeer connections unstable.

If others are finding XP works OK with LW, try talking to your ISP, or changing your gnutella port to some really high number, like 20400 or something like that.

Sorry for the interruption--thought it might be worth a try.
