I've realized that If I use free floating and a high Damping value, the particles gets an instable movement and finally spread out.
The critical value for the Damping is 48. Below 48 the particles stay on (as they should be) and above 48 they get instable.

In the sample file I've move the particle layer around a curve and I've used those values to try to create a trail of particles.
I was very surprised when I inserted 60 on the Damping force and obtained a running group of particles.
