Hi, Yes, I too prefere to go back to 4.04 when I need that extra CPU power. It's also much more stable than 4.1.1 on my Celeron400@450 128mb AW8. And I would not trust 4.1.1 for a recording session with performing musicians. Regards Per Boysen From: "DJKS" <krazys@...> Dear Luggers, Any of you having this matter? maybve there is something inside Logic setup preference or other? my LAWP CPU meter and power is more good in LAWP 4.04 than 4.1! I also can use more tracks and plug in when use 4.04! any Idea? regards, Sandi
