We confirm significant enhancement of Delta I=1/2 transitions observed in experiments, although a few large systematic uncertainties remain in our predictions: higher-order chiral corrections and lattice spacing dependence. The estimate of epsilon-prime parameter is further complicated by the problem of matching lattice and continuum operators.RevTeX, 5 pages, 5 figures, uses epsf, proceedings from DPF'99 conferenceHigh Energy Physics - Latticetext
