  While it is possible to find examples of field theories with a spontaneously
broken symmetry at high temperature, in renormalizable supersymmetric models
any internal symmetry gets always restored. Recently, a counterexample was
suggested in the context of nonrenormalizable supersymmetric theories. We show
that non negligible higher loop effects actually restore the symmetry, without
compromising the validity of perturbation theory. We give some arguments as to
why the proposed mechanism should not work in general.
