Having read with some interest about the activity monitor, I eagerly browsed into my apps\utilities folder and tried to fire it up. Not sure what I'm missing but it looks as if it's initializing and then just goes away. I tried the fairly useless macrumors search and then google but didn't get any hits for my particular problem. The one thing I'm wondering about is a widget that I downloaded to monitor core temps - could it be interfering with the activity monitor? Any help would be greatly appreciated.
