An effective classical Lagrangian for the Yang-Mills field, as proposed by
Pagels and Tomboulis, is investigated. It is found that previously known
solutions to the field equations in Euclidean space-time are unstable. In
a Minkowskian version of the model, screening solutions with an infrared-finite
energy are shown to exist, in spite of a divergent effective coupling for
small fields.
