I have small problem with stamp tool / photoshop CS3 on Mac Pro /
I can't use stamp tool, I tried to clone but doesn't work, in the 'History' there are shown all clone steps but picture is still the same.
Probably I ticked off same setting but I don't have a clue what :(
I have been using PS since 8 years but I have never had problem like this 
If there is someone who can help me would be thankful
