What exactly are you selecting? This will not work with layers that have full document size...
Hello and thanks for answering.
I remember the all days, when I used PS C3. I added a layer, make some graphics on it and if for some reason I needed to select th whole layer, I just did it by Ctrl-click on it and see how the selection edges appear in the layer. That way, I can modify the selection, for example, if I needed to smooth it or make some other operation.
By following the same procedure it did not work in CS6.
For instance, I needed to draw a smoothed border around the layer.
Finally I solved it by placing 4 guides in each edge of the layer, and then making use of the selection tool, but that is not the idea. The ideal would be to select the layer as I did in CS3.
