Abstract

After a brief review of recent data that confirm qualitative and quantitative predictions for resolved photon processes, a possible problem with the implementation of initial state showering in existing Monte Carlo event generators is pointed out. It is argued that this is responsible for the rather poor description of the jet rapidity distribution measured by the H1 collaboration at HERA.
