"Click to Add Text" Auto-insertion

Is there any way to turn off the auto-inserting of a Text Box? I made a template that doesn't use a "full slide" text box, and whenever I click randomly to either deselect a currently selected item or accidently, Storyline 360 slaps down a text box without any input.

Can I turn this behavior off? If it can't be turned off, how can I avoid this. I find myself deleting 20 of these a session when creating. Its only a problem because when it slaps this text box down, often it is above other items on the slide, and I can't just "click through" to the important bits beneath. So I have to find an edge, select the Text Box as a whole, and whack the delete key on it.
