Hi... I just noticed that if I have the Type Cover on, I can't seem to lock the auto-rotation of the screen from the Charms menu. But if I take it off, then that works. This means that if the auto-rotate lock is off and the Type cover is attached, and you turn the orientation of the Surface, the screen rotates. The only way to stop this is to take off the Type cover, which somehow mysteriously allows me to lock/ unlock the screen rotation from the Charms Menu (in the usual manner) and then re-attach the Type Cover. Surely this is not the way this is meant to be working, is it?
