Password Authentication for WebDAVs

Hello - I recently installed winscp561setup
I have configured to my webDAV shares and can connect but it's annoying me because it always asks for password twice. I would like to fix this before I install on users desktops.
I have already combed your forum for answers and I DID set the Tools dropdown - Preferences - Security tab to "Remember password for duration of session." Anything else I need to change?

Please help if you can, thanks so much!
