Just remember that if you change the background color then it changes for all other Frames. So to change the background, add a rectangle to cover the entire canvas and drag it to the bottom of the Layers panel. Lock it so it doesn't shift when you move things around.
Each Frame is independent of the others. If you delete an object in one Frame it does not affect any other Frame.
The first movie will show you how to get the samples from Fireworks and ready for the client to view.
The second movie movie I use Photoshop CS2 to make an image viewer for the client to view your samples. You won't believe how easy and fast it is! The client will be able to easily compare each sample and even approve or not AND leave you feedback on each image. They can then send you their feedback via email.
Once you get your clients feedback you can make the changes and prepare for the web.
