[vox-tech] the mouse's wheel b/w the buttons doesn't work!

[Hai Yi]

Hi there:

When I use the browser (or any other mouse-laden apps) to surf the
Internet, I found that the mouse's wheel in b/w the buttons doesn't
work, meaning I can't scroll up/down by moving it so each time I need
to grab the scroolbar to do so.

I believe its a problem of mouse configuration. But can anyone
enlighten me with some idea? Like, how to fine-tune a mouse under
Debian?

Thanks,
Hai
