From my own limited testing, I've found that once logged in, Internet Explorer will lag in displaying the main mail screen and it doesn't display the contents of the Inbox until it's been clicked on the Folders list.  Also, when logging off, the redirect to the login page fails.  I would like to get confirmation of this bug from other people.  Obviously, a fix would be welcomed as well.  This occurs even with the Pop-up Blocker turned off.
