DNN version 7.2.2.  How can I add the DNN html editor to a custom module.  In other posts from years ago there are examples, but they do not work for me.

I've registered the control in my module view.ascx:

%@RegisterTagPrefix="dnn"TagName="TextEditor"Src="~/controls/TextEditor.ascx"%

I've added the element to my html.

<dnn:TextEditorid="txtContent"runat="server"height="400"width="500"/>

The editor displays on the page, but none of the tool bar icon's are active.  Keyboard shortcuts do work though, but only in IE, not FF or Chrome.
