Internet Explorer is denying access to a <frame> because it is on some other domain

This is an IE-specific security measure, preventing what is called "cross-domain scripting".



Briefly: when the login <form> is inside some <frame> and this <frame> is hosted on some other domain (other than the current domain), then IE does not allow scripting access to that <frame> (and that's why 1Password cannot touch it).



Whenever this happens, our advice is to use [url="http://help.agilebits.com/1Password_Windows/auto-type.html"]Auto-Type[/url] or a different web browser:
