so the last few days my mouse has been acting up, it was the one that came with the computer which is like 3 and one half years old, so i decided to get a new mouse, an optic one which would be much easier, so i got one that was supposed to be plug and play....and that's when all hell broke loose, well i tried a bunch of things and nothing seemed to work, after about 45 minutes i realized that i had plugged it into the wrong ps2 port.......i am so not a geek.......sheeeshhhh!!!!!...well everything is working fine now but i need to adjust to the new scroll wheel which is much smoother but slower then the old one.......
