I had FB2K running for several hours yesterday playing one playlist. (an M3u streamed from NAS).
I had it set to Shuffle tracks but I noticed repeated tracks at times. I didn't do anything, just left it playing. When I came to shut it down I noticed that there were now three instances of the same playlist loaded.
Why? Could that be the cause of the repeated tracks? (No, there are no repeats in the playlist).
