I am seeing some issues using IE 6.0 vs Firefox 1.5. Firefox is my normal browser but some people using IE are reporting problems.
In my testing if I am logged in as a user in firefox and hit the refresh button I stay logged in. If I hit the refresh button in IE I am logged out with the only indication being that my user name is no longer visible at the login/logout link at the top. I tested this on the jforum.net forum and I do not see the same problem (refresh works with both browsers) so I'm not sure what is going on with my site. One difference is that I have some forums hidden if you are not logged in. I don't know if this causes a difference. If I hit refresh with firefox I am not logged out.
When I am logged in as admin with IE and click the open moderation options link I get booted out with a message saying I don't have permission. This only happens on the forums that are hidden from users who are not logged in. For forums that are open to everyone I can open the moderation options in IE without problem. With firefox I can open the moderation options when logged in as admin for any forum and delete or move messages without problem.
