Yes very odd,
Looking at my original example I do not get the no display if I take the steps @jonathan took with ids after introducing a new layout.
But the project does not play right. To me it looks like turn.js is only meant for a single instance. I think internally it is using ids that you have no control over.
I do see an api to remove or destroy an instance but could not get that to work. ( my thought was we could kill one instance on layout change and create a new one )
Your best bet is to contact the developer or try another library. I only used turn.js because it was to hand when I was helping in the other thread..
