Left-click not working consistently

Adding my post to to the pile in the hope that Dell is paying attention to this forum...  I just received a new XPS 17 a couple of weeks ago.  I'm having the same issue with the touch pad.  Left-click works about 2/3 of the time.  I have the most success by moving another finger around the pad without lifting it BEFORE attempting the left-click.  But even that frequently fails.
