I'm experiencing an issue with Django's messaging framework, but only on one specific network. Two users have reported the issue on their office network, but if they access the site via a different network (e.g. their home network), everything runs smoothly.
The issue is simply that messages don't get 'cleared' after being viewed. So once a message has been created, it will persist across requests until the user has lots of messages piling up on the screen.
I just wondered if anyone had any other ideas about what might cause something like this?
