Thanks Helen.

I guess I really must get my head fully around transactions....the
subject seems so arcane. Is there a quick concise Guide for "Dummies"?

I was under the impression that triggers and stored procedures
automatically run in their own transactions and that they either fully
complete or give an error and roll back. Also, if they call other
stored procedures they all execute as a single transaction under the
calling procedure?

Is the Next Transaction figure indicative of a problem?
