Hi all
Tina, if you are simply double-clicking the CHM file to open
it, note that it will simply open to whatever tab was visible when
you closed it last. Sure you can configure the TOC to be the
default tab, but that will only work the very first time the user
opens it. If your user switches to the Index and has that tab
visible and closes the CHM, it will open to the Index when they
open it again.
If your CHM file is connected to an application, your
application developer can open it in a fashion where the TOC is
present regardless of how it was last closed.
Hopefully this helps... Rick
