Two Songs playing at same time after upgrade to 3.5

I have been using Raduga 3.1 for over a year and have had great success. I upgraded to 3.5 right after it was released and love it too. There is one problem though. Every so so often it will play two songs at the same time. Once the songs end the next song plays and everything is ok. It has nothing to do with the particular song as I can back the playlist up and repeat the combination and it doesn't do it. I can't seem to duplicate this error myself. It's really frustrating and sounds bad. This started after the upgrade to 3.5
