  We study the finite temperature localization transition in the spectrum of
the overlap Dirac operator. Simulating the quenched approximation of QCD, we
calculate the mobility edge, separating localized and delocalized modes in the
spectrum. We do this at several temperatures just above the deconfining
transition and by extrapolation we determine the temperature where the mobility
edge vanishes and localized modes completely disappear from the spectrum. We
find that this temperature, where even the lowest Dirac eigenmodes become
delocalized, coincides with the critical temperature of the deconfining
transition. This result, together with our previously obtained similar findings
for staggered fermions shows that quark localization at the deconfining
temperature is independent of the fermion discretization, suggesting that
deconfinement and localization of the lowest Dirac eigenmodes are closely
related phenomena.
