You can walk back and forward when inventory is open, look up how it is done.

Thanks for the tipp
I have tried to find it out by looking in the config of the UI_f PBO.But no luck so far.

When you put enableSimulation = 1; to the dialog config (on the same level where idd is), player will be able to move.

Ok Tried it, it dosen't work

Ah, it seems you're opening the display using createDialog, which locks the movement.
Use createDisplay and it will work fine:
(finddisplay 46) createdisplay "COMMROSE_HUD";

(parent display 46 is the mission display; you can alternatively return it using [] call bis_fnc_displayMission)
