jogdial and KDE

Hi all .. .. I've just installed SuSE 8.2 on my U1. Using KDE (3.1) I notice that the jogdial scroll and click events are handled by KDE - which would be great if I didn't want my own application to handle those. Does anybody know where these events are being processed? KDE or X? And, how can I turn this feature off? Cheers, sjb
