I've had my 3" happ blue translucent trackball up and running for only 3 or 4 days now and it's starting to sound funny.
By that I mean when you spin it realy fast it's like "wwwhhhhiiiiirrrrrrrrrrrr   clickclick click   click     click        click"  all that in a matter of 3 seconds or so.
I opened it up, checked for debris, fealt the rollers where the ball touches them... I just can't find anything wrong with it???   Is it normal?  Is it a new ball thing?  Will it get better?
