Question about Microsoft Trackball Optical USB PS/2 Wheel Mouse MSX0870346
Msft optical trackball (5 key) has high resistance to movement of ball. Seems that the 3 metal balls supporting trackball all have flattened tops where they contact the trackball! Anyone know of a source of replacement support balls.
I forgot to mention one other possibility. It's a bit messy, but it sometimes helps...at least in the short term. A friend of mine found that if you eat some fried (basically 'greasy') chicken with your hands and them rub the grease on the ball it works better for awhile. Unfortunately it also tends to gather more dirt into the sunken areas around the metal nubs quicker and the ball movement becomes sticky again rather soon.

Are you sure the metal support nubs have flattened? My experience has been that either they slowly sink into the plastic or that the upper and lower plastic nub supports wear down (which tends to make the ball loose in the carrier assembly). Either way, when the ball gets sticky for me I ensure the metal nubs and the sunken areas around them are clean, then clean the ball with water and find a soft cloth to buff the ball until it is not sticky.
If the metal nubs have indeed flattened you may wish to try removing them and putting them in with the flat side toward the plastic (so you have the round side facing out) - this is assuming they are completely round.
I wish I had a better answer for you. I've have several of the MS TB Optical and only one lasted for a more than a year or so (before the problems mentioned above cropped up). Sadly they are nearly impossible to find and usually very expensive if you can find a new one.
Now if I could only find a way to fix the sudden rapid up/down scrolling mine does occasionally. I've taken it apart and cleaned everything but it still does it :(
