Same prob that you all are reporting ... Mac 10.1.2 ... one Ultrapeer (can't seem to disable it) ... now I'm seeing tens of megabytes of data versus terabytes on previous versions of Limewire. I started a thread a few days ago over in the Limewire Mac OSX forum ... no response there either. The problem is also being discussed in various platform fora all around the web. A very bad rep is rapidly building for what heretofore has been an excellent product.
