We show that the Feynman propagator in the light-cone gauge with theMandelstam-Leibbrandt prescription has a logarithmic growth for large$\tilde{n}\cdot x$ which is related to the presence of a residual gaugeinvariance. Furthermore, we show that the retarded propagator for the$\tilde{n}\cdot A$ component of the gauge field develops a coordinate dependentmass which is inversely proportional to the magnitude of the transversecoordinate. We argue that this unphysical behavior may be eliminated by fixingthe residual gauge degrees of freedom.Comment: RevTex, 5 pages, comments added, version to be published in Physical  Review
