If you look under Image>Mode in the pse 12 editor, what does it say?
If you click on RGB Color and 8 Bits/Channel, does that make a difference?
A screenshot with an image open, might give us something to go on.
that seemed to work!rgb color turned it on, but 8 bits channel didn't lite up but I'm going to try it now and see if it works to edit the photo, thanks so much if it worksif not I'll let you know! Sharon
