Hiding the cursor on the video window???

hi there, i'm actually asking this question for a friend who uses this software (my knowledge of it is limited but i am planning on getting into Max MSP)

I just want to know if there is a way to hide the mouse cursor on the video window in jitter?
It is for an artwork called "Lazy Susan" by a South African artist Johan Van Der Schijff which uses Jitter in conjunction with motion sensors to turn a robot with a video screen to face the viewer where ever they might move.

Here is a link to the gallery and exhibition: http://www.bell-roberts.com/pages/gallery_currentexhib.html

appreciate it\
