The window auto closes fine, but DW finds an error in this tag: <body onload="closeMe()">. Here is complete script:
<script>
var howLong=10000;
t = null;
function closeMe(){
t = setTimeout("self.close()",howLong);
}
</script>
</head>
<body onload="closeMe()">
blah blah blah
</body>
<script>
var howLong=10000;
t = null;
function closeMe(){
t = setTimeout("self.close()",howLong);
}
</script>
</head>
<body onload="closeMe()">
blah blah blah
</body>
