最后轮到我们思考了：如果这个CLSID是一个危险的 ActiveX 对象，如果progid涉及到以前那个 DirectX 渲染溢出～～～～

再联想到一件事情，
我试了试

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
<param name="movie" value="C:\Windows\help\tours\mmtour\intro.swf">
</object>

有效

但是

<object classid="progid:ShockwaveFlash.ShockwaveFlash">
<param name="movie" value="C:\Windows\help\tours\mmtour\intro.swf">
</object>

就不行，奇怪～
