Quantizing free fields on curved spaces requires the introduction of a conserved product for modes which is not the usual one. We discuss how this is also necessary in open string when the space is flat but the boundary conditions change with time.Finally we describe a mismatch between the asymptotic in and out states and the exact solution.
