8 buttons mouse!

[Guldo K <guldo@tiscali.it>]

Hello.
I've been gifted with a Lo@@tech Mx700.
It's awesome, it works nicely, with the usual 3 buttons (2 + wheel),
but I'd really like to get all the buttons to work too...
I looked for instructions, and found about xbindkeys and xmacroplay:
#####
In an xterm or konsole, execute "xbindkeys -k".  Then press the media
key you'd like to bind to a key combination.  You will see something
like this:

"NoCommand"
    m:0x10 + c:176
    Mod2 + NoSymbol
#####
But this does not work for me. It does work just for the keyboard.
Pressing mouse buttons I get no response at all.
How can I fix it?

Thanks a lot,

Guldo
