  We present a numerical study of the ghost propagators in Landau gauge for
SU(2) and SU(3) gauge theories at $\beta$=2.7 and $\beta$=6.0, respectively.
Analyzing different lattice sizes up to $32^4$, we find small finite size
effects. Down to the smallest available momenta, we observe no evidence for
dipole behaviour of the ghost propagators.
