It's not possible to block it with pure AS3. Your only option is to inject JS into the document via ExternalInterface. This won't require your users to add anything to their page beyond the SWF embed code; it just requires your embed code to include allowScriptAccess as sameDomain or all. Here's an example utility that enables this:

Here, I created a small lib which works on all kind of flash plugins (including chrome Pepper flash) and MAC-OS

It consists of one AS3 file and you won't need to add anything to your site (html) directory
