Antwoord op "why is my Track Pad jumpy?"I have had this problem for a while this winter (it’s March now). Tried different pad settings, cleaning the pad, etc. No help. I noticed one day that it worked OK for about 15 minutes after I had washed dishes, then went bonkers again. Then we had a warm day with a lot of rain and it worked OK. I decided static electricity had something to do with it. I tried a cell phone stylus instead of my finger. Worked OK. Since I sometimes get a static shock when I touch the laptop case I tried keeping my other hand in contact with the case, worked OK. Still looking for a really good solution, but I’m close. Being grounded while trackpadding will probably do the trick. Also, one of those bedside humidifiers would likely be a solution.
