在as2的時代，只有onRelease下的getURL纔會被認爲是一次完整的點擊，onPress就會被攔截

到了navigateToURL的時代，即使你監聽一個MouseEvent.CLICK事件，他也會被攔截，緣由我如今也不知道，誰知道的話能夠跟帖

那麼怎麼解決as3彈出一個_blank不被攔截呢，3個條件

1.判斷瀏覽器的版本，若是是firefox和其餘什麼opera啥的就直接navigateToURL，若是是IE的話就調用window.open
2.必須監聽MouseEvent.CLICK事件，若是是MouseEvent.DOWN啥的我就不敢保證了
3.wmode屬性必須設置成opaque,Transparent的話我沒試過，你們能夠試試，反正window確定不行

這3個條件知足了，才能保證彈出的新頁面不被攔截！！！！！！！！！！
