DoIT staff have received a number of reports from faculty and students regarding incompatibilities between Blackboard and some of the newer versions of web browsers. Examples include the gradecenter not loading completely, documents not being accessible, and quiz links not working. As previously reported, the version of Blackboard we run (Bb Learn 9.1 SP 2) is fixed, whereas web browsers are not. The workaround for this known issue is to use one of the officially supported browsers.
