Not to be more grumpy than usual (trying to
as grumpy
as usual

) BUT WHAT THE HECK are you doing?
I mean, your last post you were unable to install a new driver for the mouse due to a conflict of unknown nature, what happened next?
Can you see how between these:

For some reason, going into Safe Mode and attempting to remove the mice from the Device Manager didn't work. I got a error saying that the registry is corrupt and had to be restored from a good backup copy.

I did install Microsoft IntelliPoint 4.01, selected the Wheel Mouse and I checked the Control Panel in the Mouse settings and it only detected it either a Microsoft Mouse or a Basic Mouse.
SOmething must have happened or you may have somehow a "mixed set" of drivers installed.

If I didn't make any sense, let me know and I'll explain more.
Rest assured, you did NOT

Update: I even tried out the Pilot Mouse Wheel Scroll v1.0 driver and it failed to detect the middle button mouse/scroll wheel. Speaking of the middle button mouse/scroll wheel, it's not a ordinary one. Instead of scrolling up and down with the wheel. Pressing the middle button up or down scrolls the page up or down.
I am eager to understand how you can press a button
up 
Have you got an actual picture of the actual Mitsumi mouse?
Is it like this one?
