I keep finding that the Refmac version from 5.4.0034 is more "stable"
at least with full anisotropic refinement at 1.35 Å resolution. The R-
factor stays relatively similar and there is a slow decrease of R-
free with R-work. It doesn't jump around compared with an identical
refinement in current version 5.4.0066.

Has anyone else noticed this?
