Hi!1) While I press my Key Events, os x makes a system alert sound … how can i fix that?
2) And can I make the mouse invisible?
1) Can't reproduce it. Could you share (an abstraction) of your file with us?
Anyway, you could try to use an invisible text-input field, and set the input.focus onLoad.
2) document.body.style.cursor = "none"
I also have this problem now when the Canvas is detached (v74). Arrow keys and most of the Num Keys are not affected, though. Attached Canvas is fine.
