In CS2 the background surrounding the selection/mask displays as a pattern of small gray and white squares, which I usually prefer for initial review of a selection as a mask. Yes, I can go the mask panel in CS4 and switch background views but none utilize the gray/white pattern as used by default in CS2.
Can this behavior be changed? I've tried manipulating preferences to no avail and cannot seem to locate any options to change the default display options.
If that shows the checkerboard, then there is something else going on (like maybe having a black layer underneath?).
