How to deny to the ToolTip moving the Mouse?

Question

I override the OnMouseMove method, like this:

Private Shared OurToolTip As New ToolTip

Protected Overrides Sub OnMouseMove(ByVal e As MouseEventArgs)
  MyBase.OnMouseMove(e)

  OurToolTip.Show(e.Location.ToString(), Me, _ 
                  e.Location.X + 16, e.Location.Y, 2000)
End Sub

I trace this function (with a tracepoint).

When I move the mouse over the form, and then stop moving, the function is traced(from 2 to 2 seconds) however independent of if I move or not the mouse!

Apparently the tooltip.Show/Hide generates a new mouseMove event(?!), so is there a way to "fix" the mouse, and display the tooltip for only 2 seconds?
