MORE Qs about Photo Soft 2000

I have pasted part of one image onto another & merged the layers. Then I’ve been adding colors & shadow. When I try to save the image, I get a little box telling me it cannot be saved. I checked the LAYER menu & MERGE LAYERS is not highlighted, so now I can’t save my image. What am I doing wrong this time?
Thanks in advance for all who reply–I’ve gotten more help here than anywhere else in the past! :slight_smile:
