Keeping changed state between layers
In the atteched example (a modified storyline template) I have designed it so that the close X appears when its state is changed.
This is controlled by a variable being updated which is triggered when all the layers have been visited.
This seems to work first time through, but is reset to hidden on the other layers when you return to another layer. I have tried the other "Revisits" options on the Layer Properties, but that causes the radio buttons to misbehave.
