i'm lacking in technical jargon knowledge, so excuse the elementary phrasing
of this question.  i have a relatively new mouse (about 2 months old) that
has already gotten to the point where it's having trouble moving the
cursor.  a few people and i have already taken out the ball and dusted out
the interior; however, it's still acting up such that i have to pick up the
mouse two or three times just to move to certain places sometimes.  i opened
up the mouse again and found that the little roller that moves the cursor up
and down is the culprit.  it doesn't appear dirty at all.  in fact, i don't
see any dust particles and there's no noticeable buildup.  but whenever i
try to finger it to move the cursor, the cursor doesn't move very far for
the first few revolutions.  the left-right roller is still fine.  does
anyone know what could be wrong with it?  i'm thinking that either it's
still dirty and maybe i should pull out the cotton swabs and rubbing alcohol
(is that adviseable?) or there's a loose connection somewhere.  any advice
would be appreciated.  thanks.
