The vortex dynamics of a Tl(2)Ba(2)CaCu(2)O(8+delta) thin film has been measured by electrical resistivity and I-V characteristics. The temperature T*(B) defined from a vortex-glass analysis of the resistivity in the vortex liquid state using the Vogel-Fulcher relation is shown to be consistent with a vortex-glass-like scaling of the I-V characteristics in the high dissipation regime. Below T*, there is however a significant temperature range in which the flux creep does not vanish at low currents. This suggests that the transition into a glassy vortex state is cut off at some length scale.
