Copy Data to Another Schema generates Access Violation (57703)

In the schema browser, I execute the "COPY DATA to ANOTHER SCHEMA" feature.
I checked Truncate destination tables, Use reuse storage option, Disable Constraints, Enable Constraints.

A reproducible Access Violation is created:
Access violation at address XXXXXXXX in module 'toad.exe'. Read of address XXXXXXXX.

WORKAROUND:

Uncheck the Enable Constraints option.

STATUS:

Waiting for fix in a future version of Toad for Oracle.

Problem persists in Toad for Oracle v.10.0
