UPDATE DAY 3: My mouse is back to full and robust health. Twisting the wire in his nose to defeat the short was the cure.....it's almost unreal how well it's working and looking back, how long I put up with it acting up. My computing experience is carefree again. My advice for anybody reading this with mouse issues is to simply take it apart and look at it...if it's acquired as much crud as my did over 7 years, simply clean it up. Just be careful....look at it before you go to work on it so you remember how it goes back together.....I know one guy who takes things apart inside a clear plastic bag so flying parts can't escape.
