Dim base layer when other layer is showing
I am in need of some assistance. In my course, I have a slide with three layers: a base layer with two buttons. When the learner clicks the first button, it launches the next layer. When they close that, it returns them to the base layer. When they click the second button, it takes them to the third layer.
I would like the base layer to be dimmed when they click each button and launch the new layer so as not to distract from what is going on in this new layer. I thought this was an automatic process, but it doesn't seem to be working. Am I missing something, or do I need to add transparent boxes over the items in the base layer when each new layer is shown?
Thanks so much!
