Hi again
Sorry, but the nature of these beasties is that the state is
not retained. This is because with the normal
TOC/Index/Search/Glossary buttons, the state is retained to show
what is currently visible in the navigation pane. For custom
buttons, all you will ever see is the rollover state. This is
because once you click, the navigation pane doesn't normally
change. The buttons only evoke an action, such as loading a topic
or opening a URL.
Sorry, I'm unaware of a way to alter the code to make the
state persist. Maybe someone super good at JavaScript will jump in
here and enlighten all of us.
Cheers... Rick
