mouse cursor on blank screen

Dear Forum,
I want to present a blank screen (after asking participants to click on a screen with a visual analogue scale) but once I have defined participant input to include ‘mouse click’ the mouse cursor appears on the blank screen. I have tried to define ‘correct response’ for this screen as a button press but the cursor remains. How do I get rid of the mouse cursor?
Thank you

Within Participant Input for “Mouse or Touch Screen”, there is an Options tab next to the Responses tab. Here you will see there is an option to not display the mouse cursor on screen.
