So, if your not familiar with Tablet windows, there's this on-screen keyboard that runs when the log-in window is up. the idea is, since you don't have a real keyboard, you just tap on the keys on the screen with the pen and that's how you enter your password.
my virtual-L on my virtual keyboard just broke. it wasn't a dead spot on the screen, since I could drag the keyboard around and no matter where it was, the lowercase "l" wasn't working, upper-case worked fine, just not lower. weird
