i tried the latest boxcryptor version and have reinstall it several times, however i just cannot type password when i want to login, either online account or local account.
the screenshots are as follow:
you can see that the password are not masked with "*" but the real value, and when backspace, boxcryptor crash.
i had the same issue on all of my Win10 boxes, & i found uninstalling it completely, rebooting, & reinstalling was the only fix.
unfortunately, we can not reproduce this behaviour on our machines.
Please try asdfasdfs advice and completely uninstall, reboot and reinstall Boxcryptor.
