I did a clean install of Lion last week. Before I installed any applications or made any personal preference changes I updated the Lion with all software updates. However after thinking this was a near perfect/clean install after I week I seem to experience lots of spinning beach balls. My wife notices it a lot when she's checking her school web email, which she seems to lose her cursor for several minutes with beach balls. I don't know what's going on...I ran verify disk permissions with no change. Ideas?
