CPU usage freezes for some process, till process restart. I have seen this problem on different versions of System Explorer. My current version:

I've got CPU display freezes with 'utorrent.exe', 'firefox.exe', 'SearchIndexer.exe' till now.

All details on the screenshot (you can check CPU usage with ProcessExplorer up top on the screenshot):

As you can see CPU usage of 'firefox.exe' fixed on some random number and doesn't changing in time. Just after process restart everything works fine for random time. I believe that this problem is linked with sleep/hibernation/hybrid sleep.
I check it few times, problem almost every time after awaik from sleep (I'm using hybrid sleep)
