Hello! I think I might have a good fix for this. I have had my Pearl for about 19 months, without a replacement. I have had mine stop going down, and just recently it stopped going to the left. sometimes if I push hard on it and move it around, that kind of snaps it out of it, but today I got thinking that maybe the surface finish was getting too smooth. Remember, when it's brand new, it's sort of coarse? Anyway, I know keyboards I have had start out with a dull finish and get glossy over time, from just wear of the material. So, I took a large piece of cardboard, put it face down, so the trackball would be touching it, and just moved it around fairly fast, pressing not extremely hard, but firmly. side to side, up and down, in circles, just to try and scuff the surface every so slightly. I figure, if the sensors need a little bit of coarseness to pick up the motion of the ball, (as opposed to a mouseball, because a mouseball interfaces with small wheels in three directions), I thought maybe this would help.
After doing this, my track ball seems to be working perfectly in all directions. I'm not sure if the coarseness of the cardboard actually cleans the BALL, or if the ball is worn smooth, and the cardboard actually scuffs the surface just enough to help the sensors, but my trackball is working perfectly now.
