Popups being blocked in IE

Hi All,

I am using AS2.0 and SWFObject to integrate an audio player into a website. I have built a button that launches the player into a seperate window so that people can surf the site and listen to the music simultaneously. There is only one problem!! In IE the window is being block by the browser’s inbuilt popup blocker. I have tested other sites that feature similar functionality and popups are not blocked!?

Has anyone experienced this issue before and do you have a workaround?

Site I am referring to = http://universalmusic.net.au/taylorswift/
