I think also InBetween report this if you take away the priority swith in the ini file. Inbetween lower the process class with the priority switch. Thread priority are passed too the engine automatic as InBetween sees them. This class switch is for engine that isn't possible to lower with thread priority, search thread isn't the main thread or/and started for each search. Internal Windows have 31 level of priority mixed up by process-classes or thread and if they are boosted (foreground). Chessmaster lower the thread priority in the Mentor engine in the same way as Fritz and Chess Assistant and probably more do it. Odd Gunnar
