"Do not show this dialog box again" option - Move dialog box

I am attempting to use WinSCP version 4.2.5 to script an unattended transfer to an SFTP server. I can establish a connection with no problems, but each time that I use the script to connect and transfer files, the "Move" dialog box appears and prompts me to confirm the transfer. Another WinSCP user - who is also using version 4.2.5 - suggested that I check the "Do not show this dialog box again" option within the "Move" dialog box. However, this option does not appear in my installation. Any advice that you could provide would be appreciated.

Thanks...

what do you mean by script? If you use WinSCP scripting, there should be no dialogs.
