It is shown that if the charginos decay into very soft leptons or hadrons + $\not{E}$ due to degeneracy/ near- degeneracy with the LSP or the sneutrino, the observability of the recently proposed signal via the single photon (+ soft particles) + $\not{E}$ channel crucially depends on the magnitude of the $\SNU$ mass due to destructive interferences in the matrix element squared. If the $\SNU$'s and, consequently, left-sleptons are relatively light, the size of the signal, previously computed in the limit $\MSNU \to \infty$ only, is drastically reduced. We present the formula for the signal cross section in a model independent way and discuss the observability of the signal at LEP 192 and NLC energies.
