The device file /dev/locator as a default was linked to /dev/hil2 in
early revisions of HP-UX.  At some point there was a change made to a
customize script that would scan through the HIL devices looking for a
two-button mouse and link that to /dev/locator.  My guess is that you
don't have the mouse as the second device on your HIL loop.  The
following program might be helpful to change /dev/locator to the correct
HIL device.
