I am using Blackboard for school and everything has been working perfectly for weeks until today. When I went to my courses page only two were available. I cleared my cache and cookies, cleared browsing history with all boxes checked, refreshed Firefox 2 times and nothing has helped. If I resize the page randomly then two more courses appear, but the fifth is still missing. When I log in through Chrome or Safari everything is there normally. What else can I do to fix this? Thanks!
