IE always at logon prompt after upgrade

Hi

I recently upgraded from version 3.7 to 4.1

I have a report that I have embed the URL to a report along with the username and password into a page and put a refresh every 30 minutes on the page, this used to work great!!!

Since the update on INTERNET EXPLORER it goes to load the report(it starts to egg time) and then bounces back to the logon page.

In Firefox it works great!!!  I know I could just just use Firefox but the user has a real need for it to be IE.

Is there anything I can change in jasperserver settings to allow this.
