Configuring of new mouse in OpenSUSE 10.3

Hello everybody!

Somebody setup my PC with openSUSE 10.3 and with a mouse with 5 buttons. Unfortunately this mouse does not work anymore, and I am trying to use a mouse with just 3 buttons. But now I cannot do a right mouse click anymore! Where and how can I configure the new mouse?

Thank you
