I Keep Getting Logged Out

After logging in and looking at a few threads I get logged out of AF. It doesn't happen all the time. But usually once a day if I am on for a while. I am still able to view AF, but I have to log back on if I want to post a message.:confused:

Only thing that comes to mind at the moment is your cookie settings... Make sure that you allow cookies for AF and see if that makes a difference.
