Fingerprint scanner does not turn activate until curtain dismissed with keyboard

[Michael Michalski]

When the screen locks or blanks I can type the password on the keyboard, hit enter and it returns me to the desktop without issue. However, when the screen is locked or blanked, the fingerprint scanner is deactivated. I have to FIRST press a key on the keyboard such as enter. Then the curtain clears, the password dialog appears and the fingerprint scanner activates. At that point I can swipe my finger over the scanner and it logs in. The issue is, if I have to press the escape key to clear the curtain and activate the fingerprint scaner, I might as well just type the password as it actually takes LESS time for me as a competant typist to enter the password and hit enter than it does for me to move my hand to the fingerprint scanner and scan it to unlock the computer. The fingerprint scanner becomes moot. We should be able to simply scan our finger over the fingerprint scanner, or at worst, touch the touchpad to wake the pc and activate the scanner. (While it would be best to be able to simply scan and wake, if you had to touch the touch pad, at least it could be done in one efortless movement.
