Arrow KEYS required click LMB

Hi everyone,

I've got a problem with my script. In first frame I have 3 image:

First image = go to frame 2

Second image = go to frame 3

Third image = go to frame 4

I can use arrow keys (left/right) to go  from frame 1 to frame 2 (example). But when I click in first frame (frame with 3 images) on image, for example 1, script go me to frame 2, I must first click LBM inside my swf, so that use arrow keys left/right.

My script in frame 1.

qrPA.addEventListener(

    MouseEvent.CLICK,

    function(e:MouseEvent):void

    {

        gotoAndPlay(2);

    }

);

qrKM.addEventListener(

    MouseEvent.CLICK,

    function(e:MouseEvent):void

    {

        gotoAndPlay(3);

    }

);

qrGK.addEventListener(

    MouseEvent.CLICK,

    function(e:MouseEvent):void

    {

        gotoAndPlay(4);

    }

);
