The miracle revealed....
Problem:
Unlucky position of (faded out) audio player, just "large" overlaps the (usually faded out) default position of the mouse pointer.
MSP works correct, if (faded out) Mouse pointer is over (faded out) audio player + mouse click --> "fade in audio player".
That is what´s going on.
Solution:
Shift audio player "large" to a position not overlapping (usually faded out) default postion of the mouse pointer, that´s it.
Now it works correct.
