REST Command Not Implemented error

I'm sure this is a simple setting that I need to change, but I can't seem to find it. When connected (FTP) I keep getting this "REST Command Not Implemented" error. Is this something I can shut off for this session?

Thanks

Sorry, I'm running v4.1.0 build 375

Hard to tell without knowing details, but I would guess that disabling keepalives may help.

This issue has been added to tracker.

Thanks. Keepalives were off.
Installed v4.0.7 and the problem went away.

Can you provide me your email address, so I can send you a new version of WinSCP to check if it fixes your problem? If you do not want to post the address here, you can send me an email. You will find it (if you log in) in my forum profile. Thanks.
