MixEditor on screen n°3, remember position problem

Hi, i’m working with 3 screens, n°1 --> Cartwall, n°2 playlist and n°3 browser and others.

MixEditor remenber position is fonctionnaly on screen n°1 but not in N°2 and N°3.

This Module is the only one, who don’t remember position on N°2 and 3

Is it possible to repair this problem?

Thank’s for the jobs!
