  Generalizing a covariant framework previously developed, it is shown that
confinement insures that meson $\to q+\bar{q}$ decay amplitudes vanish when
both quarks are on-shell. Regularization of singularities in a covariant linear
potential associated with nonzero energy transfers (i.e. $q^2=0, q^{\mu}\neq0$)
is improved.
