Just checked on the other machine, a Dell Laptop, which also has the same version running and they do not show up there either. In the View menu, the checkboxes next to each are showing a check mark but neither the grids or guides appear on the screen. The ruler does show up. Also tried changing colors on each in the Preferences dialog boxes to no avail.Just checked on the other machine, a Dell Laptop, which also has the same version running and they do not show up there either.
