Now THIS is surprising. Perhaps you only refer to CPU usage when you say "computer resources" because I would be SHOCKED if Fritz used more RAM. But, when there are no engines running (i.e. in a human vs human game, etc.), the CM GUI takes only about 5% of the CPU. In a comp vs. comp game, with just the Game Status (moves and clock) window up, the GUI takes about 7-8% of the CPU. Activating the Thinking Lines window or the Coach starts to get a bit more costly. jm
