hair don't get attached to the model

[ronkhmps]

hello
I have the DT hair tutorial and based on the tutorial I created a nurbs sphere and created a hair system on it. then as tutorial said from solvers menu I chose interactive playback but when I move the sphere, the hair paints are staying, however the red follicles are moving with the object. anyone knows what have done wrong?
thanks

What happens when you stop playback? Does the hair snap to the right place? If so it could be a system issue. There is a lot of stuff going on during interactive playback and takes a ton of power.
