WinSCP 4.0.6, Norton interface, FTP
when using the basic FTP protocol and uploading over an existing remote file the standard "Remote file already exists. Overwrite?" confirmation will appear. everything will copy as standard when confirmed but checking the "Never ask me again" will not prevent the dialog from appearing next time. this appears to only be an issue with FTP, SFTP doesn't have this problem.
possibly related, "Keep remote directory up to date" detects but doesn't upload changes for FTP connections.
