has anyone replaced the bearings the trackball rides on?
Usually they just need a good cleaning with a q-tip and some alcohol.
Soy candle wax worked!!
Ohh my god!!! Wax works
Eyeglass cleaner - the type with some kind of silicone whatever that fills in small scratches - leaves the ball and bearing-nubs almost too slippery. Sadly, wears off quickly, so flattened nubs will have to be replaced with something. Thinking maybe nylon screws, with ends filed or carved into points
