hm... then I don't know. If you send me the data and model and parameter
file (if any used) then I will have a look and may be talk to collegues
about this.

Technically, there are many ways to force the molecule to stay where you
want. But normally it shouldn't move in the first place, so it is good
to find why it is moving out of place, and if we fail to find this out
then we can force it.
