  We analyze the non--perturbative features of 2D quantum gravity defined by
stochastic regularization of the unstable matrix model showing, first, that the
WKB approximation of the well-defined quantum Fokker-Planck hamiltonian
corresponds to the semiclassical eigenvalue density of the former. The double
scaled potential exhibits an instanton--like behaviour, which is universal and
scales, but whose interpretation in terms of pure gravity is still open.
