Hello,

I'm using the WebScriptManager in Version 10.3.20103.2171 and CRM 2.0.

<form id="form1" runat="server">

   <ig:WebScriptManager ID="WebScriptManager1" runat="server"></ig:WebScriptManager>

...

I got the following error:

Runtime error in Microsoft BLOCKED SCRIPT "Sys" is undefined

at:

//<![CDATA[

));

Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);
