Problem with header selection

I am trying to select a header so that the user has the possibility to change the header title (after all, he might have made a mistake). However, I am unable to get the header object, I always get "nothing" as the header. Please find below my code. Hopefully you can tell me what I am doing wrong?

    Private Sub DiagramView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DiagramView1.MouseDoubleClick
       Dim grid As Grid = Me.FlowChart1.LaneGrid
       Dim cellBounds1 As RectangleF = RectangleF.Empty
       Dim Mousepoint As PointF = New PointF(e.X, e.Y)

       Dim ThisHeader As Header = grid.GetHeaderFromPoint(Mousepoint, cellBounds1)
       If ThisHeader Is Nothing Then
           MsgBox("No Header selected!")
       Else
           MsgBox(ThisHeader.Title & " selected! - Row: " & grid.GetRowIndex(ThisHeader))
       End If

    End Sub

Either handle the Diagram.DoubleClicked event which gives you the mouse position in document coordinates, or from the DiagramView handler call ClientToDoc to convert from pixels to document coordinates (millimeters by default).

Thank you, Stoyo, I did not realize that it was simply a matter of the units...
