UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? "Remember Me" problem in Internet Explorer?

Has anybody had trouble getting Internet Explorer to "remember" users? Firefox works just fine, but for some reason even when I try to log in on this forum at UBBCentral, it doesn't want to keep me logged in. It just takes me back to the forum list as a non-logged in user.

Not checking the "remember me" box logs in just fine too.
