How do I hide the cursor while using the letterbox scale?

Hey constructors,

my game is running in fullscreen mode and I set the cursor style to none to hide it.

I'm also using the letterbox scaling technique.

Now when I move the cursor to the position where the letterbox appears, the cursor is visible again.

How can I avoid that?

I am not sure but try this

system everytic = mouse set style to none

Lordshiva1948 Did not work. Same as before.

Someone else an idea?
