Same problem here with IE on XP. Registered and logged on users can play Windows Media type files in a topic, but when they leave the topic, they get logged off. It's got me scratching my head. I've tried changing user, forum, and global settings but to no avail. IE just doesn't keep them logged in. I sure could use some help on this one.
Firefox and Chrome works fine...
Tried IE7 again after reading this FAQ:
Why do I get logged off automatically?
If you do not check the Log me in automatically box when you login, the board will only keep you logged in for a preset time. This prevents misuse of your account by anyone else. To stay logged in, check the box during login. This is not recommended if you access the board from a shared computer, e.g. library, internet cafe, university computer lab, etc. If you do not see this checkbox, it means the board administrator has disabled this feature.
I clicked on "log me in automatically", played media files, and switched forums just fine. Logged out and back in without checking "log me in automatically". IE should have remembered me from the last session since I hadn't removed cookies...but it had already lost my identity. So, I logged in, browsed, and played media files then switched forums and it didn't kick me off this time. It's acting like it should now, with the exception of losing my identity for automatic login...
What's going on?
