Hello. I'm using a transparent overlay script which then causes a popup window to display a youtube-type video. The issue is that in Internet Explorer, when I click a link to close the popup window, the window closes and the overlay is removed but the video keeps going in the background(both audio and video). In Firefox, the window closes (and the video/audio stop, as they should) and the overly is removed. How do I cause the video to stop playing in Explorer like it does in Firefox?
