Clean the mouse underneath. Sometimes inaccuracy is due to hair, dust
and grime mucking with the opticals underneath.

Try some different mousing surfaces. Inaccurate mousing is often a
symptom of a surface that is hostile to optical mice.

If that doesn't work, try some different mice. At very least that will
exclude a faulty mouse as the cause. Also, mice send data at different
rates depending on their resolution. They are relative beasts - they
indicate how far they have moved in a quantum called a "mickey"; they
don't (unless they have special drivers) send absolute position. The
higher resolution a mouse is, the more updates it will send as it moves
and the smaller a "mickey" is.

A lo-tech solution would be to increase the text size to the point that
the inaccuracy is less noticeable.

If the issue is a physical disability on your user's part, you might
also want to try alternative pointers, such as tablets, touchpads,
trackpoints, trackballs and joysticks.

If it has to be a mouse and none of the above are workable solutions,
see if you can get someone to tweak the mouse driver. The source code
is open and free :-) That would be a very useful tweak for a great many
people, I suspect.
