I have to update an old project that uses WinHelp, so I installed RH X5 on an old XP machine. The original help file always opened in a 2-pane window with the ToC on the left and the default topic on the right. My "updated" help file only opens the ToC/Index/Search screen in a single pane. How do I get the 2-pane window to appear?

This is what I'm looking for
