Tables looking like they belong to TOAD

My client has an Oracle 10 database containing the following objects which look like they belong to TOAD:

QQUEST_COM_SCH_JOB_AUDITS

QQUEST_COM_SCH_JOB_ERRORS

QQUEST_COM_SCH_SEQ

QQUEST_COM_SCHEDULED_SCRIPTS

QUEST_COM_SCHEDULER_REP_VER

SYSTEM.TOAD_SEQ

Does anyone know what these are? I want to remove the PUBLIC access.

Thanks.

I think they are another Quest product. The TOAD_SEQ doesn’t look familiar either.
