I have a timer on a personal website that is supposed to countdown 10 seconds and then make a beeping noise. The noise is provided over rtsp. When I visit the site with my Blackberry Storm after 10 seconds, instead I always receive a prompt "Javascript: A script has requested that a new URL be loaded. Do you wish to load rtsp://mysound..." Is there a way to disable this prompt on the Blackberry storm?
I've tried different options in Browser Configuration and I have 'Allow Javascript popups' checked but the prompt still occurs.
