Hello Joshua,
Try the following code. It does not give any problems with the latest build:
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<head id="Head1" runat="server">
<title></title>
<script type="text/javascript">
function ShowRadDock(dockID)
{
var dock = $find(dockID);
dock.enableModalExtender();
}
function HideRadDock(dock, args)
{
dock.disableModalExtender();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<telerik:RadDockLayout ID="RadDockLayout1" runat="server">

<script type="text/javascript">
Telerik.Web.UI.RadDock.prototype.enableModalExtender = function()

}
this._modalExtender.show();
this.repaint();
this.updateClientState();
};
Telerik.Web.UI.RadDock.prototype.disableModalExtender = function()
{
if (this._modalExtender)
{
this._modalExtender.hide();

};
Telerik.Web.UI.RadDock.prototype.dispose = function()

if (this._modalExtender)
{
