Internet Explorer 11 font issue
IE11 will not load custom fonts when navigating directly to pages in Blackboard via the address bar or bookmarks, and will instead display Times New Roman. The issue may also occur when refreshing a page.
Blackboard is aware of the issue and recommends using Chrome, Firefox or Safari to avoid this issue.
Microsoft is aware of the issue and recommends using Microsoft Edge. They do not intend to fix the bug in Internet Explorer 11.
