Below is the code of my Master Page. When I enable ScriptManager and related tags (as shown below), IE generates error: Sys is undefined while debugging. When I disable AJAX, the error is not shown. The page and related code is working properly irrespective of the error shown or not shown.

The error shown at run-time in IE debugger is this:
Why is ScriptManager and related AJAX tags giving this error?
You are using <link> tags to include javascript files. They should be included like this:
<script type="text/javascript" src="script.js"></script>
You also have one of your last <link> tags importing a css file but its type set to javascript:
<link href="Resources/JQueryScripts/MsgBox/jquery.msgbox.css" type="text/javascript" />
Solve these problems and maybe the rest will work?
