How to smooth-out irregular mouse action

[Josef Lowder]

The mouse action on one of my computers is very irregular ("jerky") 
and I don't know how to smooth it out.  I found some adjustments in 
the "K" control center (see:  http://www.fixaim.com/mouseconfig.jpg ) 
but don't understand what is meant by "Drag Start Time" and "Drag 
Start Distance" ... should I increase or decrease the time/distance? 
Or is there some other way to adjust the mouse responsiveness?
