I'm curious, can you reproduce it without moused(8), i.e. specifying /dev/umsN in xorg.conf rather than /dev/sysmouse. This may be unrelated but my mx518 mouse produces random clicks when I move it very quickly and using moused(8), no clicks when not. > > back then hps@ guessed that my mouse requires a certain polling rate from the > host. during high cpu load the host couldn't keep up the polling rate and thus > the mouse starts producing wrong output.
