mouse problems

[Charles Malespin]

Hi all, I had to reset my xorg settings and when I rebooted it gave me
the option of choosing either the gnome mouse set up or the X mouse set
up. I picked the X set up, but now my mouse scroll wheel wont work. It
worked fine before, but I cant get it to change now. Can some one help
me enable this? Its just your standard mouse, came with my dell computer
so its pretty basic. Thanks.
