Orbiting around objects with the MMB, or ⎇ Alt LMB is working, and zooming is working with ⇧ Shift+/-,
However panning using ⇧ Shift LMB or ⎇ Alt LMB, and ⇧ Shift MMB are not functioning anymore. Neither is zooming in/out with scroll wheel. I've reset to factory defaults and restarted Blender several times.
