In the past I have always been able to create a duplicate layer, make it b/w and then invert. I have tried select/invert, and Ctrl-I. Nothing happerns. I think I am going crazy. What have I done wrong?

Do you definitely have a pixel layer (and not any other type of layer such as a Shape) targeted when pressing Ctrl-i?
Ahh, I found the problem. thank you for the info.
