Is it possible to use workers if one develops in the Flash IDE?

Question

I've been tryting to get the new concurrency feature working - I downloaded Flash CC and have the latest versions (11.7) of the player and plug-ins installed. But - none of the code from the forums or AS3 reference works (and yes, I've tweaked it so it compiles either as an external as class or as timeline code).
There are no errors, but Worker.isSupported returns false.
I'm a very confident coder (usually), but this has me completely stumped....

Yes. You should be able to use workers. Workers can only be used for background processing. There are mechanisms for communication with workers using shared properties and channels.
Check the url below.

I am also sharing a simple sample which shows usage of worker.
Loader movie which is loading the worker (LoaderMovie.swf)
package  {
          import flash.display.MovieClip;
          import flash.net.*;
          import flash.events.*;
          import flash.concurrent.*;
          import flash.utils.ByteArray;
          import flash.system.Worker;
          import flash.system.*;
          import flash.events.Event;
          public class LoaderMovie extends MovieClip {
                    private var worker:Worker;
                    public function LoaderMovie() {
                              // constructor code
                              //Load the swf for worker
                              var workerLoader:URLLoader = new URLLoader();
                              workerLoader.dataFormat = URLLoaderDataFormat.BINARY;
                              workerLoader.addEventListener(Event.COMPLETE, loadComplete);
                              workerLoader.load(new URLRequest("simpletween.swf"));
                              this.addEventListener(Event.ENTER_FRAME, handleEnterFrame);
                    public function loadComplete(evt:Event):void
                              var workerBytes:ByteArray = evt.target.data as ByteArray;
                              worker = WorkerDomain.current.createWorker(workerBytes);
                              worker.addEventListener(Event.WORKER_STATE, workerStateHandler);
                              worker.setSharedProperty("counter", 10);
                              worker.start();
                              this.play();
                    public function workerStateHandler(evt:Event)
                              if(worker.state == WorkerState.RUNNING)
                                        this.WorkerStateText.text = "Worker Running";
                              else if (worker.state == WorkerState.NEW)
                                        this.WorkerStateText.text = "Worker created";
                    public function handleEnterFrame(evt:Event)
                              if(worker)
                                        this.WorkerCounter.text = worker.getSharedProperty("counter");
The worker movie clip (simpletween.swf)
package  {
          import flash.display.MovieClip;
          import flash.net.*;
          import flash.events.*;
          import flash.system.*;
          public class simpleTween extends MovieClip {
                    public function simpleTween() {
                              // constructor code
                              this.play();
                              this.addEventListener(Event.ENTER_FRAME, handleEnterFrame);
                    public function handleEnterFrame(evt:Event)
                              var counter:int = Worker.current.getSharedProperty("counter");
                              counter = counter + 10;
                              Worker.current.setSharedProperty("counter", counter);
Hope this helps
