We implemented UltraPeers because they will (and have) dramatically increased the number of files available while using far less bandwidth than previous Gnutella implementations (for most users). They also make connecting to the network a much simpler process.

I apologize if this has not been your experience.

When you say it flashes, are you referring to the continual redraw that sometimes occurs when you expand a group of search results, or something else?

Thanks.
