Weird issue with Internet Explorer

I’m using Peter’s login redirect to send particular users to a specific page when they login. Each user has their own personal private page they need to get to and I don’t want them to see the dashboard.

It works perfectly for me when I test it in multiple browsers. But I have two users who report getting to the dashboard when they login using Internet Explorer.

I can’t replicate this issue. Can you think of any reason at all why it would not work in Internet Explorer? Is there some particular setting these users have in IE that would cause the redirect to fail?
