I guess your problems stem from calling StartTransaction to a transaction
already active (either started by you or implicitly by IBO if you've opened
a dataset having this transaction). Most of us never bother about calling
StartTransaction because IBO starts one whenever necessary - it is only
required for logical transactions, and I've never understood why separate
this from the physical transaction.
