All right! The PG in this topic i exactly the same as i linked to in this topic (Suddenly 3D buttons doesn't return to initial color in AR - #15 by RaananW) (where I suddenly had issues with 3D buttons not returning to their initial grey color once pressed).
But the function of the 3D slider and the textblock updating with the frame number was never an issue, but now suddenly is without me changing anything 
Can the issue be related to the pointer out behaviour that was solved in the other topic I linked to?
