I noticed that navigateToURL (this replaces getURL in AS2) doesn’t seem to work locally, if you want to open a link in the same window (_self). I found this note on the Adobe site. It seems that you need to set “allowScriptAccess” to “always” in the HTML parameters. This needs to be set in both the param tags as below: <param name=”allowScriptAccess” value=”always” /> and in the embed tag: <embed allowScriptAccess=”always” />
