I am trying to use the clone tool.
Following GUM, I select a brush, select the clone tool, control-click
on the part of the photo I want to copy and then move to the part I
want to modify -- the clone tool is always accompanied by a "No Entry"
sign and will do nothing.
It is a black and white photo, I have changed from grayscale to RGB,
merged layers, saved the image, restarted gimp, everything I can think
of but still a "No Entry" sign and no cloning.
Does anybody know why?
(Nothing I can find on google or groups.google.com)
