Camera and user permissions

Question

Hi,
I want to make a web app with that can take snapshot with the webcam.
When the user gives access to the camera everything is fine, however I want to handle the situation when the user denies the access to the camera.
I have two issues I wish to solve :
1) I want to be able to pop again the permission dialog using as3 on a button click (in case the user accidently pressed on "Deny" I don't want him to reload the web page if he wishes to use it (the camera is needed). I know it is possible to right click and give permission but most people don't know about it.
Is there a way to pop back the dialog. when I tried to access again the camera it didn't help.
2) It seems to me I came across some bug in flash. I want to add an EventHandler that detects if the user pressed "Allow" or "Deny".
this is how it's done :
var cam:Camera = Camera.getCamera();if (cam != null)
    cam.addEventListener(StatusEvent.STATUS, statusHandler);
    var vid:Video = new Video();
    vid.attachCamera(cam);
    addChild(vid);
function statusHandler(event:StatusEvent):void
    // This event gets dispatched when the user clicks the "Allow" or "Deny"
    // button in the Flash Player Settings dialog box.
    trace(event.code); // "Camera.Muted" or "Camera.Unmuted"
BUT, it only dispathes the "StatusEvent" when the code runs on the timeline and not in a function.
for example this DOESN'T dispatch the "StatusEvent" :
myFunc();
function myFunc()
var cam:Camera = Camera.getCamera();
if (cam != null)
cam.addEventListener(StatusEvent.STATUS, statusHandler);
var vid:Video = new Video();
vid.attachCamera(cam);
addChild(vid);
function statusHandler(event:StatusEvent):void
    // This event gets dispatched when the user clicks the "Allow" or "Deny"
    // button in the Flash Player Settings dialog box.
    trace(event.code); // "Camera.Muted" or "Camera.Unmuted"
Any ideas?
Thank you

Check the muted property to know when the user denied and activate the showSetting dialog again.
