There may be another solution. After writing the above I remembered that
ToggleBD had a similar problem which I fixed by creating all the Toolbox
objects manually. Doing it that way means you'll get the object's ID on
exit from the SWI call and hence no need for Toolbox_ObjectAutoCreated
messages.

This seems to work as I can now place Transient early in the start-up
sequence and it runs without error something it didn't do previously.

Cheers,
Fred.
