Abstract
We confirm recent results obtained in a previous work by studying the Ising spin glass at finite magnetic field in four dimensions. Differen t approaches to this problem suggest the existence of a critical line similar to that found in mean-field theory but in a universality class different of the transition at zero magnetic field. Problems due to t he strong nature of the finite-size corrections within a magnetic fiel d are also discussed.
