Links from SWF in HTML page no longer functional

(TechNote) In Flash Player 9, calling getURL (or its ActionScript 3.0 equivalent, navigateToURL) with a window name of “_self,” “_parent,” or “_top” will no longer work when the calling Flash Player movie (SWF) file is located in a different domain than its hosting HTML page, or when the HTML parameter AllowScriptAccess is set to “never.” This may interfere with the abilities of some SWF files to change the web browser location that a user is looking at.
