Thanks for your post!
Regarding the unchecking of chart counters..
I am able to reproduce this problem on one of my machines--kindly bear with me as I look into this!
Regarding the gigantic processor time..
Out of range values like this can happen sometimes because of glitches in Microsoft's implementation of performance counters (ANTS reports the same values as perfmon would). The out of range values are more likely to occur if the counters are read too frequently or at times of high system load. (The same effect will be visible in perfmon, but it's not as noticeable as perfmon overwrites previous data after a minute.)
There's not a lot that ANTS can do about this, I'm so sorry to say, as it is a problem with the Microsoft counters. :/
Please let me know if you have any further questions or concerns!
