Multiple click boxes on one slide; Pausing project

I'm using Captivate 5.5. 

I have four click boxes on a slide.  Three click boxes upon clicking show an image and then show a success caption.  The forth click box shows a success caption but also is set to "pause project until user clicks." 

Unfortunately, if any of the three click boxes are clicked it advances the playhead even though the forth click box was never clicked.  How can I pause the project until only the forth click box is activated no matter if the other three click boxes have been previously clicked?
