Slowdown and physics

So I'm trying to make a sort of bullet-time thingy for my game, but it seems that I can't slow physics objects down just by changing the object's time scale. I read somewhere that I had to change their stepping mode to framerate dependant, but that didn't change anything for me. Any ideas how to achieve this?

Also gotta mention that I'm trying to slow down only certain objects, not the entire layout's timescale.

Bump!

i think you can only slow down movement behaviors, not physics behavior.

to make a sprite movement become framerate dependant, you have to move it with something like Sprite.X+10 or Sprite.Y+10

Oh, dangit. I guess I gotta try something else, then. Maybe bullet behavior with gravity and ricochet/bounce.
