xbindkeys and multimedia buttons.

[Sblantipodi]

Hi,
I have multimedia button on my laptop and I want to use it with amarok.

This buttons works well, infact if I run xev I can see their code and configure it on xbindkeys...
The problem is that (play button has code 4) and also my mouse has code 4 for the wheel...
In this way if I configure xbindkeys to play amarok it works well with multimedia button but it plays amarok also when I use my mouse wheel

Is there a way to solve this problem?
Please help.

Thanks!
