Click box not functioning properly the second time it's clicked

I have put a click box on a slide and picked the following properties:
ON success open a url or file
Infinite attempts
display for rest of slide
show hand cursor over "hit" area
stop slide audio when clicked
The slide itself is set up to progress when a button is selected labeled next

There are other slides in the project that have the exact same click box and they function in the published project fine. In fact, I deleted the one that does not work and copied and pasted one from another slide. Is there some hidden function on the slide?

Thank you,
Karen
