Interactive Diagram icon issue

I'm using the interactive diagram icon in XOT 2.1 with 'hot spots'. I have a product label image with hot spots on top of it, when you click on the hot spots it displays info on the left as to what the label element means. The problem is, when you click anywhere else on the screen (other than the label) it erases the hotspot feedback. Since I have the audio tag as below embedded in the text, when the user clicks to play the audio the text disappears. This is not a happy thing. Anyone know how I stop the rest of the screen area from acting as a type of informal hotspot that erases the feedback from a legitimate hot spot?

Thanks
