htmlEditorExtender not loading the toolbar

Hi,

I am trying to use the html editor extender or the editor ajax controls but I am  failing at both.

If I use editor, I just get a dot on the page.

If I use a text box with the html extender, I don't see any toolbar which tels me somthing is wrong.

Here is my code below.

<asp:TextBox runat="server"
ID="txtBox1"
TextMode="MultiLine"
Columns="50"
Rows="10"
Text="Hello <b>world!</b>" />
<asp:HtmlEditorExtender
ID="htmlEditorExtender1"
TargetControlID="txtBox1"
OnClientChange="onContentsChange"
runat="server" EnableSanitization="False">
<Toolbar>
<asp:Bold />
<asp:Copy />
</Toolbar>
</asp:HtmlEditorExtender>
