Query: Strong and Radiative $D^\ast$ Decays   We use the relativistic light--front quark model to show that both strong and
radiative $D^\ast$ decays are in good agreement with the 1992 CLEO II results.
In particular the coupling for $D^{\ast}\ra D \pi$ is consistent with the
experimental upper limit. The key point is the relativistic treatment of the
quark spin.
