[AccessD] Updatable UNION?

I know, I know, I know... ;) 

Still, something is nagging at me. 

In the middle of the night, it will rush into my head, wake me up and I will
realize it had nothing at all to do with the subject at hand. <groan>

Unions are not updatable by definition, Susan, no matter what tricks you
use.  In a Union, there is no distinction between the tables the fields come
from and the names don't even have to match,just the datatypes, so there's
no way to update any of the data.
