Has anyone experienced a trackball wearing out . . . ?
This Logitech TrackMan Marble model CH11 must be 15 years
old, possibly 20, connected PS/2, running under Win98SE.
Erratic cursor behavior began suddenly this month:
1. Slow travel across the screen, I'd say half its former
speed or slower. The unit is used intensively, e.g. for
TurboCAD, Magix Audio Cleaner (software with next to
no hotkeys.)
2. Sudden lateral jumps from one window to another.
The ball, optical sensor and support bearings (three
metal pinheads) are clean and free from dust. The
ball looks different from that of the newer Marble
Mouse: the dots are blacker and appear more
distinct on the younger ball. (The balls are of
different sizes thus not interchangeable.)
