The black circle cursor that is normally present while writing character keeps changing between the normal white arrow cursor and the black circle.
It happens when there is more that one writing prompt in a row. For example, the first writing prompt will be ok, but the for the second and others consecutively following it will revert to the white arrow cursor.
It doesn't effect the writing quality, but it would be nice to have to stay one way or the other.
