I noticed that it had been removed from its download site, so I thought that my experiences reflected a bug in the program. It's back up today, and so I decided reluctantly to give it another go. The results were even worse. Besides all those same obnoxious windows, I even had difficulty closing the program. I had to End Task to shut it down.
There really isn't any reason for this program to exist. There are many other options that will perform the same functions without the problems. It uses the Gnutella protocol but its purpose is diametrically opposed to the objectives of the movement.
Trash it!
