I've found a bug(in the windows version, just to mention, dunno about the others):
1. Launch Mute
2. Wait until there is some connection quality
3. Search for something("mp3")
4. Change current tab(don't know if this step is needed)
5. Switch back to "Search"
6. Roll scroll wheel (down?)
7. Now MUTE disappears, no precess left. When restarting, you have to enter a NEW random seed(looks like settings are resetted).
Hope you cal solve it, it goes on my nerves^^
