How can I get the ToC to open automatically in Webhelp?

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.""):

if(!SendMessage(panevisible)) {

show():

}

Thanks in advance for your help.
