Dielectric constant measurements of a 
crystal are performed in the orientational glass low-temperature phase. Aging and
ergodicity breaking are studied through isothermal decays and temperature cycles. New
results are obtained on the response of the sample to temperature jumps: three processes,
with very different time scales, are put in evidence. This allows to propose
a new interpretation of previous experiments and, in particular, to present
a new solution of the paradox observed for the negative temperature cycles.
