Can't get layouts to work

I’ve followed the small tutorial in the help about creating and using a layout.

I’ve selected my new layout in the configuration but no matter when I build it still creates a standard window without unsung the layout.

I must be doing something stupid but I can’t figure it out.

I think you’re referring to the Making Images With Background Pictures section of the manual. Does your layout have a background picture, or does it only position the icons? Do you have more than one configuration?
