Trying to turn off screen turning on when buttons are pressed

[mvourlias]

Hello all. This may seem like a stupid question but since I've upgraded from WM5 to WM6 the checkbox under Settings, Backlight where you can have the backlight turn on or off when keys are pressed isn't there anymore. I'd like to be able to turn this setting on again so that the screen does NOT turn on when I touch the keys. I assume there's a way to do this.
Thanks!
