When my app starts up, it opens a floating window containing a table
view. As the table is brought to life from the Nib, it posts a
"selection changed" notification to its delegate. At that time it
hasn't had its data initialised from the data model so the selected
row is 0. This causes an undesirable change to the data model.
Here's the stack trace of the table initialisation.

This seems to be a race condition - before the table is ready I can't
populate it and set the correct row to match my data model, but
because of this notification the data model gets prematurely changed
to an incorrect row.
I can't see why it sends this notification at this point - anyone care
to explain? Anyway, how can I stop it?
cheers, Graham
