Interestingly enough, I had already tried the backslash escape character
in several combinations all to no avail. At your suggestion, I have used
the recommended string noted below in a slightly altered script.

<script language="JScript">
function Launch() {
var sExec = "\"c:\WSH Script\TechNet Script Center\scriptcenter.chm\"";
var oShell = new ActiveXObject("WScript.Shell");
oShell.run (sExec, 1);
var oShell = 0;
}
</script>

When I first click the 'Clickme' button I get the error:

The system cannot find the file spedified.

However, if I click 'Click me' once again, the program launches.

Oddly enough, I had to remove the [bWaitOnReturn] value of False. I kept
getting an error 'False is undefined' and the script would not run at all.
You'll also notice that 'CreateObject' in VBS has been replaced with
'new ActiveXObject' which is apparently the only way it will work in JScript.

If you have any further suggestions, I am all ears and sincerely hope that I
have not 'worn out my welcome' in what must appear to be an obsessive pursuit.

Cheerio & many thanks,
Ray
