Layer closes when tab on slide master is clicked
I have a series of tabs/menu items across the bottom of the screen that are available on all slides in the course. These are on a slide master.
The learner clicks a tab and a list of topics displays that they can choose from. The list of topics displays on top of the current screen and learner can choose a new topic or can close the list by clicking the menu item again. The screen stays intact unless they choose another topic by clicking on it.
On the base layer of screens, it works as designed. But when a layer is displaying, the screen reverts back to the base layer of that screen as soon as they click a tab and topics display.
Ideas on how to keep the layer displayed, ie how to leave the screen as-is when the learner is looking at what's available elsewhere until they click a topic? Since it works on the base layer, seems like it should work for a layer, too??
