No, it rarely works the first time. It seems that when the screen goes dark from power saving, and I hit the bar to bring it back into view, the bar key stroke is interpreted as a letter or something, and then pressing enter doesn't work. When I use my mouse to bring back my screen, I can open the password simply by pressing enter. To save time, I always press Esc then enter. Esc seems to bring it back to zero again.
