D-Command ES + Fader Madule Fader Problems

[FedericoF]

Hi to all.
My name is Federico; I have a problem with my D-Command ES, and the Fader Module.

I explain :

If I run the TEST (Vegas, Cycle, Group etc. etc.) all works fine. All Faders move without any problem.

If I create a new Session, with for example 24 Tracks, all Faders go in the right position.

If I move the Faders from the Computer (moving them with the mouse), all works fine, and their position is perfect on Icon. I can also move them very fast. (for example I activate ALL Group, and I move them very fast, and they works very fine)

Now I explain the problem :

If I move the faders, from ICON, they works very bad... seems blocked.

I run Pro Tools 10.
How can I solve this?......

Thank you very much!
