How do you fix a broken mouse wheel?

[Moe Zart]

It can only scroll up, not down.

I mean physically it can scroll both up and down, but the result on the computer is always scrolling up. Meaning: Scroll wheel up it scrolls up, scroll wheel down it scroll up.

Never mind. I just took out the mouse wheel and destroyed it out of frustration.

That's one way to fix it.
