I got the new window to open up with the new CHM now...
As a follow up, it seems I need to define the new window with
the specific TOC and Index of the new CHM. I there a way to define
a window that picks up the related TOC and Index of the chm that it
opens(in this way, a single window type gets created, so that when
I get a new subsytem, I do not have to keep adding/creating new
windows, which makes me have to redistribute the main system
help...which is what I am trying to avoid)
