Hello! As you can see, I'm pretty new to the world of MusicBee, and what a great player it is! The "shuffle different artists" option is absolutely fantastic! No more Itunes system-hog for me!
I was having this same problem, and it was pretty bad, with MB freezing up multiple times. I was looking for help in this thread and, somehow, managed to click on another thread dealing with a different issue. In that thread, someone suggested unclicking the "remove silence" option. I decided to unclick it to see if it would help with the freezing and, in the last week, MB hasn't frozen on me a single time! If you're having the freezing problem, give that a shot.
