I have a D partition on my system drive which I have encrypted with bitlocker. I do not have the System partition encrypted. I can't turn on bitlocker if I don't have the TypeCover hooked up. When the unlock screen pops up, I touch the on screen keyboard icon to enter the password, then the unlock pop-up disappears. I touch pop-up to enter the password then the on screen keyboard disappears. Unless I am doing something wrong, this is a MAJOR flaw in the OS. Does anyone have any ideas on how to stop this behavior?
