MAC OS to El Capitan upgraded. Try edit my folders or login passwords as previously and screen goes blank. Shows in view mode however.
Seems like it won't allow any changes to previously existing folders or logins. I could always click edit before on my login and click on the password area and it would show me the password. Now it goes blank so I cancel out in case I loose that password. Copy still works for the password.
When in each folder, clicking on edit in both the title area and the field area both go blank. Exit out and view mode works fine.
Works fine on my new iPhone 6 plus.
