Hi Guys,

A client has reported an issue with IE9 where he has logged in to edit pages and is now unable to sign out. IE9 re-directs to the home page and remains logged in. I have cleared the sites cache which hasn't helped.

Unfortunately the client works away with his laptop and so I haven't had the chance to look over his IE9 settings. And I'm using a Mac so I can't try and replicate the issue at the moment.

I'm sure this is an IE9 issue rather than a C5 issue.

My research so far has taken me here:-

There's also mention of HP SimplePass 2011 here:-

but my client's machine isn't an HP.

Does anyone have any further thoughts or ideas?

Cheers,
