Thank you, @cgrunenberg.
Previously, as suggested in other threads, I did open the directory for DTP in Script Editor, where I found ‘window’ and ‘viewer window.’ I tried multiple times to use syntax including ‘open window,’ ‘new window,’ ‘new viewer window,’ etc, but unfortunately my syntax must be failing. I did figure out how to open a window, but it only gives the contained elements in icon view, and its a window with no title bar, side bar or other elements of my standard DTP windows, and its size is quite different. Sorry, I don’t know what to call this window.
I am just not understanding how to open a new window just like my other DTP windows, and then direct it to the pertinent group. I am not sure what the window I am getting is called, or if there is a way to change its appearance to match my other windows.
