Bug reports without an attached log file are usually useless.
IMHO you cannot get around that. 'su' needs PTY for security reasons. So to say: you need to be human to run 'su', and WinSCP is not a human :-) For example you cannot create file with your password and redirect it as input to 'su'. It will detect that. If you find some solution, let me know, I'm interested.
su requires user input ( the password! ), how do you get around that? Or am I missing something obvious?
You cannot execute 'su' in WinSCP session. At least most of the servers refuse to execute 'su' for session with not allocated PTY. But you may try it from 'Console' window.
