Dell ended up replacing my original laptop with a refurbished unit and have had no further issues.  I've also received a response to my inquiry about the redesign Dell has implemented and the repair to those still having the issues.  They have redesigned the trackpad and also has a gasket below the pad to eliminate the static build up that seems to be the cause of strange behaviors. I'd reach out to Dell to request this repair be made to your laptop.
I finally got Dell to recognize the touchpad has issues. I've resorted to using a wireless mouse.  The dell technician will be here today to replace the touchpad. I'm hopeful I'll be one of the lucky ones and the replacement resolves the crazy behavior the current one has.  It started a few days after I received, and have been trying to get resolved since then.  Wish me luck
