Some more information about this:

My "transactions" table's order status updates to "shipped" just fine, but
the status for each line item in the "orderline" table remains at "pending".
The error.log reports this:

/cgi-bin/ic493/admin/order Attempt to set orderline::status::2527-1 in
read-only table

Why would it be kept from updating the orderline table?  I'm using the
default DB, and no catalog-level order_status.html page.
