Forgive me for giving an obtuse answer...
I absolutely HATE the wheel mouse, for the very reason that you are mentioning. My solution was simply to get rid of the wheel mouse, and go back to the standard 3-button mouse that came with the workstation.
I realize that this doesn't suit most peoples' desire for "bells and whistles," But the simple fact is, they weren't made for CAD programs. And, last I looked, there weren't any major manufacturers who were shipping the wheel mouse as standard equipment with a CAD intended workstation.
Of course, I'm also the guy who still longs for the days when workstations came with the old "click" type keyboards. Man, those sure were wonderful... I've never typed on anything so nice, and it seemed like I could type about 100 words per minute on them, whereas I can only do about 50 on a "soft touch" keyboard. I really drove people nuts with the clatter! (but who cares - what a wonderful piece of equipment!)
Oh, sorry... No the mouse is a pain. Deal with it, or replace it with equipment that has a propensity towards CAD...
