  The disorder driven quantum Hall to insulator transition is investigated for
a two-dimensional lattice system. We consider a Gaussian correlated random
potential, study the behaviour of the current carrying states and trace their
energetical position when the disorder strength is increased. Our results
qualitatively resemble those obtained previously for exponentially correlated
disorder potentials. We find both the downward movement of the anti-Chern
states as well as the floating up of the Chern states across the Landau gap
which is sometimes masked by the global broadening of the tight binding band.
