Joe, not to make you feel bad, but if you do a search here for "FreeWheel" you'll find that the phenomenon of the scroll wheel not working in the VBE is the subject of at least ten threads (and probably more where members recommend a different download to fix).
I guess Richard's code is so succint that he does not need to scroll so much. That or else he uses a really, really old mouse that doesn't have a wheel...
