Thanks, Bruno - I'm pretty sure the driver is the latest as I upgraded as soon as I received the system which was only about 2 weeks ago.  I had to dig into the availability of a newer driver at that time as I got a message the first time I opened Vue with the new machine that my video card was not compatible with Vue and Fixed Hardware Pipeline mode was going to be used.

When I posted my message, I didn't realize that this weird behavior doesn't only happen with Vue.  I was downloading Vue's newest build from e-on's site and the same thing happened (Vue was not open - only Firefox).  Could it be a memory leak? I don't know anything about memory leaks.
