That is the function of the mouse wheel. You can turn it off (search
this NG on the topic and you can find the module to turn the wheel off)
OR
In this thread, you will see that he stumbled onto a hardware solution
to the mouse wheel.

It's the software for the mouse (and incidentally the
keyboard). The setup facility in the mouse software (not the microsoft
mouse
settings in control panel) has a "system default ,(intelimouse)"
option and
a setting called "enhanced scroll mode". It doesn't explain what
exactly
"enhanced scroll mode" is, but when that option is selected the wheel
scrolls
inside the form. When "system default "is selected it scrolls between
records. This is the case even when I connected a conventional (cable
and
rollerball) mouse. Might be worth talking with the manufacturers and
see if
they can explain. from what you've said there might be a whole new
market for
their product!
