  We report large-scale simulations of the resistively-shunted Josephson
junction array in strip geometry. As the strip width increases, the voltage
first decreases following the dynamic scaling ansatz proposed by Minnhagen {\it
et al.} [Phys. Rev. Lett. {\bf 74}, 3672 (1995)], and then rises towards the
asymptotic value predicted by Ambegaokar {\it et al.} [Phys. Rev. Lett. {\bf
40}, 783 (1978)]. The nonmonotonic size-dependence is attributed to shortened
life time of free vortices in narrow strips, and points to the danger of
single-scale analysis applied to a charge-neutral superfluid state.
