    unwanted gridlines



      Windows 7 Photoshop CS5 extended

      See image to show unwanted gridlines.  They appear in any file  I  open (psd, jpg, png.

      I have run this version of Photoshop for years, but this problem just began suddenly.

      How do get rid of these unwanted gridlines?
