%X We study a polydisperse soft-spheres model for colloids by means of microcanonical Monte Carlo simulations. We consider a polydispersity as high as 24%. Although solidification occurs, neither a crystal nor an amorphous state are thermodynamically stable. A finite size scaling analysis reveals that in the thermodynamic limit:  a the fluid-solid transition is rather a crystal-amorphous phase-separation,  b such phase-separation is preceded by the dynamic glass transition, and  c small and big particles arrange themselves in the two phases according to a complex pattern not predicted by any fractionation scenario.
