Hi John,
I have seen two other machines with similar small numerical noise
issues and I will post a patch in a little while. But notice that due
to the plot/* refactoring present in 3.2.1.rc0 (which should be out
tongiht) the patch needs to be based on that tree, so let me or
somebody else with access to that tree do the fix.
Cheers,
Michael
