Audio stops when external link clicked on?

Hi

I have a V/O audio file which read out eveything which is shown on a slide. Some of my slides have external links to either websites or PDF downloads and if they are clicked on while the audio is still going it will stop. Is there anyway of the user to still be able to click on external links and have the audio still play?

I am using Captivate 5.5.

Cheers
