I have also at times set up a small terminal window tailing /var/log/messages so that I could monitor the disconnect messages in real time. I hold no doubts at all about being able to recognise when one of these disconnections occurs. Out of interest I just examined the messages written when I manually disconnect the mouse and they're identical to what's written during one of these events. As per my other message to Jeremy I'll see what transpires after I remove my moused configuration from /etc/rc.conf. Wayne
