After successfully implementing a Login control on a page with a custom skin and logging in to an account, the Logout button dosent respond, it refreshes the page without logging the user out.

Has anybody encountered this problem before?

When i give the url localhost/dotnetnuke/Logoff.aspx

it changes to http://localhost/dotnetnuke/Welcome/t...
and gives me the same page with an empty pane ..

I've written a URL-rewrite method myself, but it doesn't override an existing method.
the Login control is normally registered in the skin :

Page header:
<%@ Control Language="vb" AutoEventWireup="false" Explicit="True" Inherits="DotNetNuke.UI.Skins.Skin" %>

<%@ Register TagPrefix="dnn" TagName="USER" Src="~/Admin/Skins/User.ascx" %>
<%@ Register TagPrefix="dnn" TagName="Login" Src="~/Admin/Skins/login.ascx" %>

On page:

<% If (Request.IsAuthenticated) Then%>
|
<% End If%>
