Possible to obtain mouse x,y screen coordinates within an ObjectMouseOver event?

Question

I'm trying to build a custom tooltip that will follow the mouse whenever the user is hovering anywhere over an object in the scene (rather than have the tooltip appear in a fixed location relative to the object). Is there any way to get the current mouse location from the 'ObjectMouseOver' event? Or from the tb instance itself?

Thanks!
