moving actors didn't stand still!

MarcoCol

I have a few moving actors in my scene. If the player touch and move the actor, it works, but I can see, that if the player doesn't touch, the actor still moves. That only maybe a pixel per few seconds, but it doesn't look well.

So is there a chance to set this movement really to 0?

I set:
density: 0
friction: 5
Bounciness: 0
Drag 500

Also fixed rotation is not checked.
And in actor, collide with the player is set.
