I've just noticed that something seems to have changed when I first add a new photoshop layer after the background layer. In the past it seems I remember that when I clicked on the new layer icon at the bottom of the layers panel, the new layer would appear as a transparent (checkerboard) layer. Now that no longer happens - I just get a normal blank new layer. And I can't figure out how to make a new transparent layer show up. It's probably simple but at the moment I'm stumped. Any ideas? Thanks.
