Setting up 3d mouse with rhino 5

unhandled

#1

Hi there. I am trying to setup my 3Dconnecion 3d mouse with rhino 5 for mac. when i first started using it everything seemed inverted so i changed the preferences and after a lot of fiddling it seems to work…until i move underneath the cPlane and then the controls become inverted again. if anyone could offer some advice on how to use this it would be great. i want the controls to function as if i am in a helicopter flying around the 3d model rather than revolving the model around as if it is in my hand. thanks.
