Since update from 6.25 to 6.50 I get on session.Starttransaction an error:

Can not perform operation on active transaction

I see in DBMonitor no open transaction
In 6.25 it works well.

Any hint for me or is it a bug ?

Transaction can be started automatically if you lock a record in dataset (for example, when you edit a record, and the LockMode property of TOraQuery is set to lmLockImmediate). Check that no records are locked when you call the StartTransaction method.
