Hey, just need to know why this wont work in IE

http://www.akmphoto.net/order_microsite.html

When you click on the btns the pop-up doesnt work…notice it works PERFECTLY in Firefox…any ideas??

code for the btns in flash are

  **Code:**			  green_btn.onRelease = function() {

getURL(“javascript:Launch(‘http://www.akmphoto.net/micro_site_2.html’, 776, 480)”);
};

And the Java script used is

  **Code:**			  <script language="JavaScript">

function Launch(page, width, height) {
OpenWin = this.open(page, “Silver Micro Site”, “toolbar=no, menubar=no ,location=no, scrollbars=no, resizable=no, width=” + width + “, height=” + height + “, top=” + (screen.height/2 - height/2) + “, left=” + (screen.width/2 - width/2) + “”");
}
</script>
