あなたの問題はおそらくこれです：

addEventListener(Event.ENTER_FRAME,myFunction);

を呼び出してもstop()、myFunctionアプリケーションのフレーム レートに従ってフレームごとに 1 回実行し続けます。したがって、フレーム レートが 24 に設定されている場合、myFunction は毎秒 24 回実行されます。つまり、これらすべてのリスナーを毎秒 24 回何度も追加していることになります。（これらのマウスイベントリスナーの後に終了すると仮定するmyFunctionと、クロージングが欠落して}いるため、推測する必要があります）。

ENTER_FRAMEまた、そのリスナーを削除することは決してないため、(gotoAndStop行を介して)プログラムの別の部分に移動した後でも、myFunction毎秒 24 回呼び出され続けます。1009 エラーは、typewriter_pieceインスタンスが存在しない別のフレームに移動した可能性がありますが、ENTER_FRAME ハンドラーはその関数を繰り返し実行しています。

次のコードを使用します。

typewriter_piece1.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece1);
typewriter_piece1.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece1);
typewriter_piece2.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece2); 
typewriter_piece2.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece2);
typewriter_piece3.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece3);
typewriter_piece3.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece3);
typewriter_piece4.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece4);
typewriter_piece4.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece4);
typewriter_piece5.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece5);
typewriter_piece5.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece5);
typewriter_piece6.addEventListener(MouseEvent.MOUSE_DOWN, start_drag_piece6);
typewriter_piece6.addEventListener(MouseEvent.MOUSE_UP, stop_drag_piece6);
stop();

myFunction から (フレーム上で実行されるため)、ENTER_FRAME リスナーのコード行を削除します。

効率と健全性のためのヒントとして、次のことを試してください。

//This will add all your listeners with just 3 lines of code
for(var i:int=1;i<7;i++){
    this["typewriter_piece"+i].addEventListener(MouseEvent.MOUSE_DOWN, startDrag);
}

//you can use the same drag handler function, and get the item with event.currentTarget
function startDrag(event:MouseEvent):void {
    var typewriter:MovieClip = event.currentTarget as MovieClip; //gets the one that was clicked/mouse downed

    var target:MovieClip = getTarget(typewriter); //get the appropriate target

    if(target.hitTestObject(typewriter)){
        typewriter.stopDrag();
        //do the rest
    }
}

//get the appropriate target
function getTarget(typeWriter:MovieClip):MovieClip {
    for(var i:int=1;i<7;i++){
        if(typeWriter == this["typewriter_piece"+i]){
            return this["Target"+i];
        }
    }
}

myfunction 関数を削除してみてください。機能である限り、プログラム全体で有効です。それを取り出すと、特定のフレームに対してのみライブになります。そうすれば、あなたが退去するとすぐに、プログラムはこのコードを尋ねたり、チェックしたり、気にしたりしなくなります。コードの上部にあるフレーム入力コマンドにより、フレームに入るとすぐにライブになります。他のすべてをそのままにしておきます...解決策が機能したことを確認できてうれしいです!!! :p
