The two problems are the mouse jumping to the lower right corner (with log saying it sets to x=0, y-0) and occasionally, the mouse tracks a finger that is hovering over the track pad.  We can often get the problem to go away by wiping a palm across the entire track pad several times or by holding a finger firmly on the track pad.  Neither of these solutions works reliably every time, but so far repeating these and wiping our fingers on something else have always resulted in a useable trackpad with less than 10 attempts (I haven't been counting).  The behavior strongly suggests to me that there is a charge or capacitor problem.
