    Ive been checking out the AM lately especially when MP goes sluggish. I have the questions that's always bugged me. In the CPU column. How can the %CPU be more than 100? I see one app at 115 abd another ilia 53 and another 43, 69, 24, 18 and so on. I mean WTF??

    Because you have a multi-core CPU. So for example if an app is using 60% of each of two cores, that readout would show 120%.
