Good.

I am not sure - but this seems related to another thread (Refreshing
and IBODataset).

I have known for a while that there are some limitations in the
synchronisation between the internal and external datasets, but I am
not certain exactly what those limitations are or how they can be
worked around. (Since I dont use TIBO* stuff I have never spent the
time to get familiar with the code.)

Not as far as I know.

I think we may have to wait for Jason's return to get some help on
this, it is not an area that I know much about and I dont have the
time to do a detailed investigation.
