CS5 CPU utilisation

[Mr-White]

CS5 has a habit of hammering core 4 to a 100% of my Q9550, the weird thing is it doesn't do it all the time but when it does it could just be sitting there will no images open. Then as soon as CS5 is closed the cpu usage drops to 1-10% in line with the other 3 cores.

Process Monitor might be your best bet to shed some light on it, or a trip to the Adobe forums to see if anyone else has experienced similar.
