Hey!
Uff, yes. When Germán and I did this project: http://ss3.gemstone.com/ss/KinematicTemplates.html, we had to fight a lot with that.
Take a look at the code.

In the package KinematicTemplates-FFI there's a class Invokator that changes the cursor position at OS level:

Invokator(class)>>apiCGWarpMouseCursorPosition: aCGPoint
    "CGError CGWarpMouseCursorPosition(CGPoint newCursorPosition);"
    < apicall: void 'CGWarpMouseCursorPosition' ( CGPoint )  module: 'CoreGraphics.framework'>  
    ^ self externalCallFailed.   

And then, an example of usage:

Invokator apiCGWarpMouseCursorPosition: (CGPoint from: 30@30 ).

Tricky detail: if after evaluating that example you print World activeHand position, it will not be 30@30, so you also have to update the activeHand's position:

World activeHand position: 30@30.

Tell me if you need something else, or if this isn't really what you needed :P

Cheers,
Carla.
