Flash:How to successfully open a new window in Firefox w/o being blocked???

I have tried unsuccessfully in ActionScript 3 to open a new window within my Flash app using navigateToURL w/o triggering the Firefox pop-up blocker.  This is a desired action by the user, triggered by MouseEvent.CLICK, allowScriptAccess=true,  and based on Firefox’s dom.popup_allowed_events, it should work w/o being blocked.  I’ve googled other possibilities (http://skovalyov.blogspot.com/2007/01/how-to-prevent-pop-up-blocking-in.html) but haven’t found a single option that appears to work correctly for me.   The other detail of this is that the HTML is loading the SWF and all the content from another domain, which works perfectly. Its just that Firefox is giving me fits.

Anyone got any better ideas?

I came across this URL and the method proposed here worked perfectly for me.
