does anyone know how to maintain the users scroll position on DNN pages?

i have pages which have modules "below the horizon" and it's very irritating to have the user returned to the top of the page on updates.

i can see in the default.aspx and default.vb pages that there "something" written which appears to be addressing this. for example, in the aspx page i can see:

    <dnn:form id="form" runat="server" ENCTYPE="multipart/form-data" style="height: 100%;" autocomplete="off">
        <asp:Label ID="SkinError" runat="server" CssClass="NormalRed" Visible="False"></asp:Label>
        <asp:PlaceHolder ID="SkinPlaceHolder" runat="server" />
        <input id="ScrollTop" runat="server" name="ScrollTop" type="hidden" />
        <input id="__dnnVariable" runat="server" name="__dnnVariable" type="hidden" />
    </dnn:form>
 

and in the vb page there is:

        Public Property PageScrollTop() As Integer
            Get
                If ScrollTop.Value.Length > 0 AndAlso IsNumeric(ScrollTop.Value) Then
                    Return CInt(ScrollTop.Value)
                End If
            End Get
            Set(ByVal Value As Integer)
                ScrollTop.Value = Value.ToString
            End Set
        End Property
 

along with some commented out code:

        ''' <summary>
        ''' Initialize the Scrolltop html control which controls the open / closed nature of each module
        ''' </summary>
        ''' <param name="sender"></param>
        ''' <param name="e"></param>
        ''' <remarks>
        ''' </remarks>
        ''' <history>
        '''  [sun1] 1/19/2004 Created
        '''  [jhenning] 3/23/2005 No longer passing in parameter to __dnn_setScrollTop, instead pulling value from textbox on client
        ''' </history>
 

and this:

        Public Property PageScrollTop() As Integer
            Get
                If ScrollTop.Value.Length > 0 AndAlso IsNumeric(ScrollTop.Value) Then
                    Return CInt(ScrollTop.Value)
                End If
            End Get
            Set(ByVal Value As Integer)
                ScrollTop.Value = Value.ToString
            End Set
        End Property
 

but it seems the ScrollTop value is always 0

anyone tackled this?
