Voice Over Issue

I have 2007 and I did record individual .swf files for each page. The problem only seems to be when they click from the page (on a button) and it takes them to a pop up window. As long as they simply click the forward button the audio stops. I tried an action to stop audio on click but it did not work.I have 2007 and I did record individual .swf files for each page.
