问题：s：Label上的点击和触摸事件性能不佳。Adobe Flash Builder移动点击/触摸事件
我使用最新的AIR版本和Flash Builder 4.6开发移动应用程序。
这是代码：
<s:Group horizontalCenter="10" top="200">
<s:VGroup>
<s:VGroup id="wortundtafelstriche">
<s:HGroup id="wortalign" >
<s:Label id="wort1" visible="false" textAlign="center" width="43" color="0xffffff" />
<s:Label id="wort2" visible="false" width="30" color="0xffffff" />
<s:Label id="wort3" visible="false" width="30" color="0xffffff" />
<s:Label id="wort4" visible="false" width="30" color="0xffffff" />

click事件的功能：
protected function makeunvisible(obj:Object):void
{
obj.visible = false;
}
这是很简单的。
如果有人点击一个字母（s：Label），该字母应该是不可见的。
令人沮丧的事实是，当我点击一个字母时，隐形的方法并不总是被调用。
有时我必须在调用该方法之前单击十次。
我也试图与触摸事件，并且没有鼠标事件的发送和仅使用鼠标事件更好的结果...
