Assessment Feedback - "next" button not working in Chrome

In our assessment, when you select an option and submit your answer, you are presented with feedback that displays in a pop-up (the content exists on its own slide). On the feedback slide, we want users to click the Next button to advance to the next question. This functionality works perfectly in IE (10) but doesn't work at all in Chrome (51.0.2704.103). The only way to clear the Feedback screen and advance to the next slide in Chrome is to click the "x" in the upper right of the window. Does anyone know if there is a fix for this?

I've included two screen shots in case it helps. The first shows how the feedback displays. The second shows the action associated with the Next button to close the window.
