When I pretend I am a user of the online help system I have
developed using MS HTML Help, the relevant page opens but the TOC
doesn't expand to expose the page name on the left. Is this a
limitation of the HTML Help program?
Off the top of my head, I'd guess that your Help file is
calling a window that doesn't include the TOC. Without more
details, though, it's tough to say for certain. Can you provide
more information?
