Nah, that's how I was instantiating it, as a new sniff.

Now, in the ASP.net book i have they say to put a ClassName="" attribute in the ascx tag, like such:

<%@ Control Inherits="uCtrlPreview" src="uCtrlPreview.vb" ClassName="SomeOtherName" %>

saying that it is needed in case we dynamically create the control on a page.
