Why is Safari using 97 percent of my CPU?

I never thought that Firefox would use less system resources than Safari.

The last few days of my MacBook Air have been a little wonky. I couldn't figure it out until today when I noticed that Safari was using anywhere from 90-97 percent of my CPU. I also noticed a few times when the CPU was running over 100 percent.

Please note that I was using Microsoft Office, but I didn't feel good about it. We have a board meeting tomorrow and I needed to review some stuff. I still can't figure out how to get the formula bar where I want it in Excel 2008 and it makes me crazy.

I had been blaming Firefox for the machine slowdown, so my apologies to the Mozilla team.
