how to program mouse buttons

Hi All,

I have been searching for an answer, but surprised not to find anything.

How do I program the extra buttons on my mouse? All I find system/preferences are the very basics.

Thank You

i use btnx http://www.ollisalonen.com/btnx/
on my logitech wireless mouse ( 12 button ) 9 are set

I've used evrouter, on mice and other devices.

Thanks for the info. I hope to give it a try later this evening.
