将下面的代码保存成html文件，用DW打开后，DW会自动将frame的src改成错误的值。如何防止DW这种自作聪明的行为？
<!doctype html><html><head>
<meta charset="UTF-8" />
<title>sys.Name</title>
</head>
<frameset rows="80,*,20" frameborder="0" border="0">
<frame src="?/Admin/Head" scrolling="no" />
<frameset cols="180,7,*">
<frame src="?/Admin/Side" scrolling="no" />
<frame scrolling="no" noresize="true" />
<frame src="?/Info/Index/0" scrolling="yes" name="Main" />
</frameset>
<frame scrolling="no" />
</frameset>
</html>
