Problem with IE8 popup blocker and Windowless mode

Question

My team is having popup blocker issue, which is crippling our system where a large range of users are now complaining that their links or buttons will not open in IE7 or IE8 and results in the pop-up blocker message.
Our Flash application's embed code needed wmode set to windowless ('opaque' or 'transparent') since we need to place floating HTML objects over the Flash application. But all links (within static text content) with target set to '_blank' or a custom name and also all navigateToURL() methods with the same target values are now resulting in IE pop-up blocker message once the window mode was changed to 'opaque' (same result also with 'transparent').
We have a AS3 work around for the navigateToURL() method but no solutions for 100s of pages of simple HTML content contributed by users that have links as well as our own Flash static-text content with links.
Here is a simple page created to demonstrate the issue - http://clients.projectmiso.net/photobiz/custom_lightbox/Test_File.html
And the ActionScript 3 code -
var clickFunction = function(){
    var targetURL:URLRequest = new URLRequest("http://www.yahoo.com");
    navigateToURL(targetURL, '_blank');
btn1.addEventListener(MouseEvent.CLICK, clickFunction);

Hi!
One thing you could try is to use MOUSE_UP instead of CLICK
( tip-source : http://www.actionscript.org/forums/showthread.php3?t=176795 )
This example uses clickTag parameter (through flashvars) instead of a hardcoded URL inside the flashfile though,
but I'm sure you get the point:
clickBtn.addEventListener(MouseEvent.MOUSE_UP, function(event: MouseEvent): void {
var sURL: String;
if ((sURL = root.loaderInfo.parameters.clickTag)) {
navigateToURL(new URLRequest(sURL), "_blank");
clickBtn.buttonMode = true;
clickBtn.useHandCursor = true;
Or you might want to have a look at this workaround :
