Logins not working on some websites

Not sure if this is the 100% right section to be posting this question, but am figuring I am close enough.

On certain websites when using Internet Explorer, specifically a website assurex.com, whenever I log in to the website, it says I have successfully logged in, but on any screen afterwards I am not logged in. It just shows the login link back in the top corner, and not the usually account management link.

When using Firefox I have no problems at all with this site.

I cannot seem to put a finger on what is causing this. I have tried different versions of Internet Explorer (6,7, and 8), installed all Windows update (Important, Software, and even Hardware), and upgraded my Flash player.

What could possibly be causing this issue?
