re why is my mouse so jumpy ms mouse in article c zs pr cs vu nl wlieftin cs vu nl liefting w writes ecktons ucs byu edu sean eckton writes i have a microsoft serial mouse and am using mouse com was using i think but switched to to see if it was any better vertical motion is nice and smooth but horizontal motion is so bad i sometimes can t click on something because my mouse jumps around i can be moving the mouse to the right with relatively uniform motion and the mouse will move smoothly for a bit then jump to the right then move smoothly for a bit then jump again maybe this time to the left about inch this is crazy i have never had so much trouble with a mouse before anyone have any solutions does microsoft think they are what everyone should be just venting steam i think i have the same problem i think it is caused by the rubber ball in the mouse which doesn t roll so smooth the detectors in the mouse notice this and whoops i hit a mine using minesweeper i think the solution will be buying a new mouse and or using a mouse pad wouter and or taking the rubber ball out of the mouse should be directions in the manual or on the bottom of the mouse and cleaning it with alcohol isopropyl i believe the same alcohol as used for cleaning your cassette deck this is good to do every so often even if you have a mouse pad dust still gets caught in the mouse and on the rubber ball as well lint and other garbage may find it s way onto the rubber ball and get into the mouse damaging the horizontal and vertical sensors hope this helps good luck sincerely robert kayman kayman cs stanford edu or cpa cs stanford edu in theory theory and practice are the same in practice they are not you mean you want the revised revision of the original revised revision revised
