We have a problem with Siebel 7.8 that whenever user gets redirected to the home screen upon session timeout the browser window can not be closed. User also can not log in or navigate away from the page by entering a different URL. The window is not halted.
There are no obvious scripts or runtime events upon application load or unload that might be causing this. My assumption is that some Siebel ActiveX messes up something in the browser event processing due to some reason.
