You cannot edit options of currently connected session. If that's what you ask for. You need to disconnect (you get a login dialog than, if it was the last opened session), edit and connect again.

Anyway, you can open the login dialog by going to Session > New Session.

Hi,

New WinSCP FTP user here... Looks like a great app so far!

When you first start WinSCP , a Login box appears that allows you to choose a saved session and also to edit its properties.

Once logged in, how do you invoke this dialog again? That is, how do I get the "saved session property edit" dialog? I couldn't seem to find a menu option or a toolbar button to bring it back up.

Thanks!
