Summary:
It is shown that the solution of the quark Dyson-Schwinger equation in QCD obtained with a gluon propagator of the form D(q) ∼ q²/[q⁴+b⁴] and a quark-gluon vertex that is free of kinematic singularities does not describe a confined particle and that there is always a value of b² = b{sub c}² such that chiral symmetry is not dynamically broken for b² > b{sub c}².
