Hi @lstarling
It does work for me, but it could be an issue with the scaling settings on your monitor (described in this post).
In the attached demo, I’ve added a circle that should appear at the same location as your mouse cursor when you use MouseGaze - do those two line up? If not, I would recommend that you follow the instructions in the post linked above to make sure your screen scale settings are 100% rather than 125% (or anything else).
