Open "Menu Options" popup event

Hi,

I need to open the popup window Options (which contains options: Open in new window, refresh, personnalize, details, ...) of the Page Title bar (the one which contains "History", "Back", "Forward" and this option popup).

I do not manage to open this popup menu.

I have tried to call the "htmlb_ShowPopupMenu()" function that is called when user clicks on the picture to open it, but it is not working (document null error).

Does somebody know how to simulate the call of this event and open this menu option ?

Thanks,

Fabien
