hi, my mighy mouse's scroll wheel stopped working and i took it apart to clean the roller things around the ball. it stopped working again so i took it apart a 2nd time, then a 3rd, all without breaking a thing, an amazing feat since most people have to break the plastic ring outer ring to get inside. well it stopped yet again so i when through the normal dissasembaly process and i lost one of the tiny magnetic rollers! anything i could use in the mouse instead of the roller? thx.
