I'm running through the tutorial because it's boring.

I get to the dummy, read the instructions.
it's facing away from me, hold M to keep it from detecting me (as holding M then moving is said to generate less noise by a huge amount.. it doesn't.)

and it detects me: crouching, prone, whatever - while holding M.

What am I doing wrong? is there any trick to this? should I uninstall the game and move on or what?

mostly, looking for people to read this and offer guidance as I'm legit stuck.
