But it also does something else for me. It makes these engines move instantly. I can use a 2 hr. time control, and after these engines get out of book, while they are thinking, clicking the checkbox will make them move instantly. Unclicking the checkbox, they will think normally. I tested this over and over so i know that is happening for me. I don't know whether this happened before the patch or not. Dave
