I went into the applications>utlities>activity monitor, & opened it, but it seemed to hang, the mouse pointer goes to the rainbow circle & could not produce any results of the laptop activity. The only thing I had open was the finder, (of which I cannot seem to ever quit.) I forced quit the activity monitor about 2-3 times after I opened it. Does it take awhile to read the activity? I can x out of the red circle in the top left corner of the finder window, but I see a small blue spot underneath the finder icon at the bottom in the dock. Does the finder just stay open? it seems to be running whenever I start the computer up. other wise everything else (other apps) seems to open up & close ok.
