Question

I can\'t seem to get this to work.

Workaround In main window added script function:

    function here() {
        alert('Welcome Back')  // seems needed to wake up document
        window.focus()
    }

In opened window invoke script function:

    function HomeTab()  {
        O = window.opener;
        if (O)
            if (O.closed)   alert('Home page has been closed')
            else    O.here()
        else alert('This tab has no home page')
    }

Works widely differently in different browsers Some will have the parent tab blink Some mark the parent tab, and you have to notice it Some you have to click on home tab the first time and you can then give it permission to go directly to home tab without a confirm box.
