I have had this ongoing problem. When my help project is embedded in our software system and you open it, the ToC is not displayed; there is just a link called "Show" that you click on to open the ToC.
My users do not think to click on the "Show" link so are baffled about how to navigate the help.
I asked this question on the forums before and one of you (perhaps Peter Grainge?) kindly sent me a script to add in the footer of help topics but sadly, it did not work.
For info, the script was:
var panevisible = new whMessage(WH_MSG_ISPANEVISIBLE.this.1.""):
Thanks in advance for your help.
The root problem is how your developers are calling the help.
If they cannot or will not fix it, I think the script was from Willam van Weelden's site.

I got around the "Show" issue by changing the wording to "Show Contents/Search/Index" by editing the .lng file.
In case Jeff's response makes you wonder exactly how to "edit the .LNG file", you click File > Project Settings > General tab > Advanced button > LNG File tab.
