latest beta notes: "To counteract any possibility of having one's keystrokes recorded when logging in to TWS, for instance from an unknown public computer, we have added a mouse-driven "keyboard" interface to the login window. To open, click Keyboard icon in the title bar of the login box. Click your mouse in the username field, and use the mouse to enter your username. By default the keyboard uses lower case. For upper case, click the UP arrow on the right side of the keyboard." will this new feature eliminate need for security card?
