I'm not sure, from what I've noticed the pointer must NOT be moving to prevent this error. In older versions of Vuen the pointer could accidentally be clicked to teleport around the Palette, and by doing that will start spamming E000. However, in your version the pointer can actually "move" , not by teleporting but by moving, so the pointer in your version will start moving and freak out, giving the error. When I played, if the pointer was sitting still and you hit ESC to reset the selection you have, it stops the error.
That's currently what I told people to do in my map.
