Gerard,

On a live dataset with a lot of user-interfacing I think you are
right. IBO uses commitretaining so the physical transaction will
maintain active until the timer shuts it down.

As far as I can see it now it would be wise to use a different
TIB_transaction component for all programmed SQL-updates and inserts.
This way the userinterfacing will not be disturbed by you executing
SQL-events. Am I right ?
