Hi Neal,
the displacement is not a bug, it's a feature... It is part of the
data scaling. It is a pain, I know. However, the pain without it is
even greater... I am sorry not to have time for the next 7 days, but I
hope that the reference manual chapter containing the key
'disabledatascaling' helps you. This key will also correct your
feature, although you certainly want to activate the data scaling
eventually..
Best regards
Christian
