Ok, the attached file is part of a tutorial that I am working on. Masking is the only technique that I have not mastered in Fireworks yet. Can someone tell me why I can not select all objects in the file so that I can mask them to the top layer??? I am working with Fireworks 3 on a Windows operating system. (I know, windows is half my problem, but it's the only thing I have).
