Stop Captivate 8 from advancing?

I have searched and read a lot of postings on this subject. No clear answer that I've found.

I am using Captivate 8 and I want the user to be able to remain on one slide and click a button as many times as they like. The button calls a javascript function.

I have two buttons on the slide. The pause for each button is time such that the button that stops playback comes first while waiting for the user to click the button containing a javascript button. I tried adding a second button with its pause timing set to stop the playback again. This works only for two clicks then the next slide loads. The click event is clearly being passed along to some higher object in the hierarchy and being interpreted as a general "continue" command. Is there any way to stop that behavior?

Looks like this was "fixed" in Cap 9 button properties, Actions tab, by the addition of a checkbox that you can uncheck to tell the system to NOT "Continue Playing the Project."

Is there no way to accomplish this in Cap 8?

Thanks,

Pete
