They never sum 100% for me, windows, linux, or otherwise. A lot of times, when nothing else is running, idle process takes over, and the time taken by this process is not included (and should not be included) in the stats. Also, on a dual CPU system, if one CPU is full and the other is empty, then the maximum reported is usually 50%. If those dual CPUs each have HT (example, recent Intel Extreme series processors, I believe) or similar technologies, and only one thread on one CPU is running, max CPU would be 25%. I could be totally wrong though. Is the CPU being used by something? (If not, then it shouldn't say much. If it is, *then* that's funky.) -- ~Mike - Just my two cents - No man is an island, and no man is unable.
