Highlight box should appear when click box is clicked.

Hello!

I created some hotspots on an image by inserting click boxes. (I did not use the template for hotspots because it seems connected to a quiz results slide, and I would like to avoid that).

When clicked, I would like a highlight box to appear (so the area clicked on the slide is marked).

So I select the click box, and under Properties I select 'Show' on succes. I then select the highlight box to be showed.

During preview, the highlight box is always visible. What should I do to make the highlight box invisible at first, and be only visible after the click box has been clicked?

I can make this happen if there's only one click box (pause project until user clicks, place highlight box later on the timeline).

But it's a problem when there are more 'hotspots' (click boxes) on the image. Then the highlight boxes appear all at once.

Thanks!
