My next question concerns photoshop CS under Mac, which gives certain Wrong report, which I have still never experienced at photoshop under Windows.
It concerns working with layers (layers).
At placing a layer from an certain image on another picture the layer touches
in the course of the version "locked" without I commission for that purpose. The report sounds: "Could not complete your request because the layer is locked".
Frequently happens this after the cover percentage (lower than 50%)of concerning layer
has been modified.
The layer can be no longer moved, increased or modified. Can anybody help to solve this problem?
