Registered logged on users will be logged off, upon switching pages, after viewing a windows media file .wvx, .wma, or .wmv...but only with group level permissions. If I generate user level permissions, it seems to work fine. On a large board, it would be way to tedious and time consuming to have to create user level permissions for every single user. See http://www.jestcountry.com/forum/viewtopic.php?f=4&t=3 if you need to test.
