We report on the dependence on temperature and disorder of the
glassy behavior observed in thin films of 
in the
strongly localized
regime. The glassy behavior is reflected as a local minimum at the cool-down
gate voltage in the conductance vs. gate-voltage, 
sweeps of
field-effect
experiments. It is shown that these non-ergodic effects are controlled by
an inverse-Arrhenius law and involves a characteristic energy which increases
with disorder.
