Ok, Mark, I have to give you kudos on this one after all. Unplugging my Logitech optical mouse did not fix it until I upgraded to the latest version of Flash from the Intrepid repos.
Here's what I did: 1. Remove flash-nonfree 2. Install Adobe Flash Player from Adobe's download site 3. Tested a site known to drive up my CPU and it still did 4. Update manager notified me that I needed to upgrade Flash so I did 5. Tested a site known to drive up my CPU and it sill did 6. Unplugged mouse and CPU use dropped right away. No problems since. Wow! Not sure yet why removing my mouse helps but Mark, thanks a ton!!
