  We point out that if the Peccei-Quinn symmetry breaking scale $F_a$ is in a
range of the hadronic axion window ($F_a\sim 10^6$GeV), the
ee$\gamma\gamma+/\!\!\!\! E_T$ event in the CDF experiment can be naturally
explained by a no-scale supergravity model with a light axino. We also stress
that the hadronic axion window still survives the intergalactic photon search,
since a large entropy production due to the decay of Polonyi field yields a
substantial dilution of the cosmic axion density.
