When we add our domain as a trusted site to IE, then the html 'title' tag is ignored and the page url is shown in the browser header bar.
Whn we remove our domain from the trusted sites list then the correct title is shown in the header bar.
This only occurs in a popup window.
Why is this?!
( I should add, this is in IE8 - same thing occurs in any mode)
Thanks to marktucks for pointing me in the right direction.
In my case the solution was to 'enable' the 'Allow script-initiated windows without size or position constraints' option in IE security settings for the Trusted Sites Zone. The title, rather than the page URL is then displayed in javascript initiated pop-ups.
I think this may be due to this security advisory where spoofing of the title bar was possible in popups http://secunia.com/advisories/14335/
