Layer auto closes in storyline with no trigger

Thanks Gerry, thanks for helping me rule those two things out, it helped me to work it out.

I had a hover trigger on an object on this layer to show a 3rd layer which did have the setting "Hide layer when user hovers out" is selected and I thought it would apply to the hovered, layer, but it instead applied it to the initial layer. Changed the trigger and it worked. Thanks
