Loss of vertical mouse movement in suntools/sunview

[Omar A. Karim]

The SUN 4/110 which I have has recently developed a marked loss of mouse
control in the vertical direction. The only way to get SOME movement is to
press hard on the pad. Rebooting and shutting off doesnt help always.
Sometimes it does help.  This problem comes and goes although today I cant
seem to get around it in any way. Are there and fellow sufferers? Can
someone offer any fix? Is this a bug-feature or simply a decay of the
system which is 0.5 yrs old? This is a standalone system with 8 Mb.

Any help will be appreciated... moving the mouse around in large circles
on the pad doesnt help.

Thanks.
