  We compute the proper real-time interaction potential between a static quark
and antiquark in classical lattice gauge theory at finite temperature. Our
central result is the determination of the screened real-part of this
potential, and we reconfirm the presence of an imaginary part. The real part is
intimately related to the back-reaction of the static sources onto the gauge
fields, incorporated via Gauss's law. Differences in the treatment of static
sources in quantum and classical lattice gauge theory are discussed.
