How can I open a new (_blank) browser window in as3?

**Opening a new window in as3 triggers popup blockers on some browsers. How do I get around this problem?

** I need a solution that will work on all browsers and all minor versions of Flash player 9. Like it worked in AS2 with:
on(release) { getURL("http://www.adobe.com", “_blank”); }

I have done some testing with different ways of opening a new window and with different "wmode"s. But have not found a generic solution that will work on all browsers. To many are blocked by browsers popup blocker. Anyone out there got a solution for me? Adobe?

I have also set up a testpage for checking different browsers. Take a look here:

Also check out the results from my testing here (green is OK, red is blocked):
