Hello,
Ok, I desinstalled the program and reinstalled clearing all the previous properties. After restarting the computer, I now works fine.
Thanks.

Of course I do it but it doesn't change anything :(

You can to select some file(s), if you want to display/change file properties.

Properties are greyed out. I'm using SFTP and running the latest version of Winscp to date.
I can't accesss properties and can't find a good answer for how to change this online.

Thanks for your help
