Is there a way to turn off or otherwise disable the below option/checkbox on the initial BitLocker dialog that pops up when you insert a BitLocker-encrypted USB key?
If the checkbox is checked -- even after characters are entered in the textbox -- the password characters are shown on the screen.
Screengrab of default BitLocker dialog with some characters entered, display shows "*****":

Screengrab once checkbox is checked, after the characters above entered, display shows "omg!kittens"

The Black Helicopters will clearly see my password if my kitten happens to pounce at an inopportune time. Seriously, this is a pretty ugly, though perhaps small, security issue in my opinion. You start typing... sneeze or get distracted... someone sitting at your desk just has to hit "Tab" then "Space" and they get the goods.
For reference, this is under Windows 7 Ultimate x64.
