Grafik Designer 9 masking problem

[Harley]

Hi,
I have a problem with masking and i do not know what i am doing wrong

That`s the way i do it:
Load a photo, select the masking tool, draw a mask within the picture. I can see it, it is active.

As soon i select fx (pencil for instance) i can still see the mask (now without the little handles) however,
then the whole picture is in pencil style - also the masked area... i want the masked area in save mode, that`s why i create a mask.
What do i do wrong ?

Maybe somebody can give me a hint ?

Sincerely
Harley
