Hi gadabout (and Peter),

After not seeing your problem I have actually managed to recreate the problem and making the four gray bars appear

I tried to force the issue by making "mistakes" and the one thing that made it happen was by hitting a song in the song picker window twice quickly and causing a glitch before the first one had loaded properly - i.e operator error

I simply reloaded the song correctly and of course the saved proper version was back without the four gray bars
