Yes.  WD-40 is not really a lubricant, but a degreaser.  Regreasing or reoiling after using WD-40 is a Good Idea.

I thought all trackballs were optical ??

Yes and no.  I believe he is talking about the kind of trackball that doesn't use rollers to sense when the ball is moved.  What I mean is there are trackballs that actually "see" the ball move and then communicate that movement to the computer.  My Logitech TrackMan Marble+ is one.  No rollers at all, it just has 3 little plastic beads that hold up the ball.  As for sensing movement there is just a window below and to the right of the ball.
Arcade trackballs turn rollers which have a wheel attached (to each direction roller) and the movement of these wheels are read and sent to the computer.

Got it, thanks !!

I'm thinking about getting an Ultimarc trackball for my next project - anyone have any luck finding a translucent ball for these?
