When using a query, I had assumed that I could update all the fields
of a row and TIB_Dataset.Modified would only be flagged as true if
the data had actually changed.

I'm finding that setting a field to the same value will set the
modified flag to true. Do I have to manually compare every field with
it's new data to detect if the row has changed?

I'm sure this wasn't the case originally, but I don't know if I've
accidently changed a property in order to give this new behaviour.

TIA
