Background process interfere with mouse NIS 2010 erratic mouse tracking

I have NIS 2010 ... installed it on an xp machine, and the machine started to have erratic mouse behavior (as if a process was running, for a split second, and then my mouse leapfrogged to another part of the screen w/o continuous tracking) ...

 

So I got a new mouse (MS 4000 wireless). Nope.

So I installed the mouse software. Nope.

So I disabled some things in NIS. Nope ...

So I got a BRAND NEW COMPUTER (I needed one anyway) ... Dell 6510 w 4 gig ram and i7 ... same problem.

 

The common denominator (new mouse, new pc) is NIS 2010.

 

What do I need to disable to get this busy-ness to stop?
