Mouse scroll wheel/button and hand dexterity

[Rick Berger <rberger rogers com>]

Are there any utilities out there that let you control whether the
scroll wheel is going just act as a scroll wheel or just as a middle
mouse button? My dexterity is such that there are times I'm scroll
through a page in Firefox and find I'm way off in web space somewhere
else because I've accidental click the wheel.  Or likewise in most
application I can't click on something because I can't hold the scroll
wheel still and click it at the same time. A utility that lets you
toggle from the keyboard the meaning of the scroll wheel would great.
