I am having fun with hover, building a simple patch that will report the name of an object when the mouse button is pressed, then report "none" when the button is released. It will report "none" when the button is pressed over an unnamed object.
This was working pretty well until hover stopped reporting "none". Now it only reports a named object, and nothing when an unnamed object is under the pointer. I don't know why it changed behavior, or how to get it to do what I want.
