Access violation at address 640BCB21 in module 'ORA805.dll'.
1. Corrupted files or installation of SQL Navigator.
2. Corrupted files or installation of Oracle client.
RESOLUTION 1: Replace the file 'ORA805.dll' with one from another computer that does not have this issue.
RESOLUTION 2: If that does not work, reinstall the Oracle client. We highly recommend upgrading to a newer Oracle client than version 8.0.5 as this was an unstable release.
RESOLUTION 3: Uninstall and reinstall SQL Navigator. Retest the issue.
RESOLUTION 4: Once the client has been reinstalled or upgraded, reinstall SQL Navigator.
