Prevent Responsive Text Pop-Outs from Appearing

Some Adobe Captivate 2017 users are reporting seeing the following icon/button on their published responsive design eLearning projects.

The button you are seeing at the bottom of your text container (smart shape or text caption) is actually by design in Adobe Captivate (2017 Release). It appears when a text container has more text than can be accommodated by your minimum font size and the size of the text container. For example, when displaying large paragraphs of text on a smaller display. Tapping the button will display a dark overlay with all the text in white, and if necessary, with a scrollbar when the amount of text is too much for the screen.  Once your learner finishes reading all the text, tapping the screen will return them to the full slide. Sometimes it seems as if the button is appearing for no reason. There are a few possibilities as to why this happens.
