Hi,

I want to use an IAT-Experiment with mouse and touch.  
If I try it on a mac with chrome and safari, it works fine.

Mac OS 12.6 + Firefox 107.0 and win10 + Edge107.0.1418.56 or Firefox 107: The mouse is invisible.  
If I press the right button I see the context menu and the mouse. I can then move the mouse to the location where it is needed. However, this is rather unprofessional.

I changed already the background color from black to red. The same problem occurs.  
After moving the mouse to the top. I can see the mouse permanently on Mac OS 12.6 + Firefox 107.0 after I press once the secondary click. In Win10 it is still the same.

These are my settings:

```auto
win = visual.Window(
    size=[1440, 900], fullscr=True, screen=0, winType='pyglet', allowStencil=False,
    monitor='testMonitor', color='black', colorSpace='rgb', blendMode='avg', useFBO=True, 
    units='height')
win.mouseVisible = True

```

Any help is appreciated.

Thanks  
Daniela

```auto
document.body.style.cursor = 'none';

```

in a code element
