Thanks, I was using the drawing tool instead of the select tool.

[Activating a selection for editing]

I'm a new user, and feel very silly after reading all the clever stuff others are doing with the software, but when I select a section of a pic to edit, it is not active, get a solid black line around it instead of a broken one. How do I activate the selection? Some guidance in the help topics on the basics for new users would be useful.
