I am a student user of Canvas. I like to use Canvas chat to communicate with my teachers and other students. However, lately when I've tried to get on, the chat will not work. I can see the history but that's all. This only happens on my school laptop, a Dell Venue Pro with windows 8. On my desktop at home I can use the chat just fine. I tried using a different browser to open chat on my laptop, but it still didn't work. I think there is something on my laptop preventing chat from opening but I don't know what. Anyone have any ideas?
