I've been having a problem with my scroll ball not working properly. It will scroll up, but not down. I use canned air and "clean" the inside, but that only lasts a few minutes. Is there a way to fix it??
If you search the forum you will find 100 threads on this. Turn the mouse upside down (after unplugging/turning off) and rub the scroll ball vigorously on a clean lint-free cloth for about 30 seconds. Does the trick for me.
