  Exploiting a five-year span of data, we present improved timing solutions for
the five millisecond pulsars known in the globular cluster NGC 6752. They
include proper motion determinations for the two outermost pulsars in the
cluster, PSR J1910-5959A and PSR J1910-5959C. The values of the proper motions
are in agreement with each other within current uncertainties, but do not match
(at 4 sigma and 2 sigma level respectively) with the value of the proper motion
of the entire globular cluster derived in the optical band. Implications of
these results for the cluster membership of the two pulsars are investigated.
Prospects for the detection of the Shapiro delay in the binary system
J1910-5959A are also discussed.
