  If the one term $(\hat \nu_e \hat \mu - \hat e \hat \nu_\mu) \hat \tau^c$ is
added to the MSSM (Minimal Supersymmetric Standard Model) superpotential, the
recently observed muon g--2 (anomalous magnetic moment) excess can be explained
very simply by a light $\tilde \nu_e$. If the soft symmetry-breaking terms
$\hat \nu_\alpha \hat h_2^0 - \hat l_\alpha \hat h_2^+$ are also added,
realistic neutrino masses (with bimaximal mixing) are generated as well.
