The dispersion relation of capillary waves in a plane moving liquid curtain is critically re-analyzed with an eye to its behavior near the origin of wavenumber space and the large-time asymptotics of the corresponding Green's function. Evidence is found that recent and less recent theories supporting the existence of a zero-wavenumber algebraic absolute instability contain serious inconsistencies.
